I recommend doing a cruise on the Thames and a day of plain old sightseeing (Big Ben, London Eye, etc). Also, if you like toy stores, you could go to Hamleys Toy Store and just check out the free demos for helicopters and such. Also, the Natural History Museum is one of the better ones if you are into museums.

my uncle is a rather well off lawyer and, when i traveled to london with him, our first night we just went out to a random sushi place right near our hotel, planning to go to a high class fancy restaurant the next night.

this sushi place was so fucking good that we just ended up going back two nights in a row. if you guys like sushi would highly recommend, although it's probably not at all close to berkeley square idk.
it's right near westminster abbey/big ben/parliament so you guys will probably be in the vicinity at some point. it's a small hole-in-the-wall type place. get the soft shell crab maki if you go.

here it is if you're interested.

edit: was probably actually fairly expensive i don't really remember because saké (which btw is pretty good here)

camden town
covent garden
regent's park
british museum
westminster area (big ben, westminster abbey, Buckingham Palace (11:30am guard changing starts), national gallery etc)
south kensington area (history and science museum)

also: hire the bicycles!!

Go see a play or two. Definitely recommend the bicycle hire, too.

This just solidifies my belief that euros can't read

Make sure you get indian food and kebabs. The plays, even if you're not really into plays, are amazing. The coolest tourist thing to do imo is go to the tower of london. All of the museums are free and worth checking out. There are tours of all the stadiums which are amazing if you're into soccer at all. Also you don't have to tip people, tax is included in prices, and change is valuable.

It's an amazing place with tons of stuff to do and simply wandering around will allow you to find something cool.

The whole area by parliament and big ben is right across from the london eye which makes it easy to see in a relatively short period of time. IIRC the tickets to the london eye can be bought in some combo with tickets to other stuff (Wax museum maybe?). So that's pretty cool.

Something maybe a little bit less touristy, at least from my experiences is the Churchill War Rooms. They are the bunkers that Churchill and his government was run out of during WWII. There is also a small sub-museum/exhibit about Churchill and his life. It doesn't take that long and is pretty cool.

If you look on google maps the war rooms are within walking distance of parliament and the london eye. It's a pretty cool area to walk through.

Other things to consider are day-trips. You can talk the train out of london to various different places and see them for the day. Last time I went with my dad out to a castle, saw the inside and then did a nice segway tour around it. Also Stonehenge+the cathedral in the same town are cool. I've also been to Greenwich which was decent. There is a old spice trading ship there + the obvious time line thingie and a museum about clocks or something. Another place was Oxford. Again me and my dad walked around town, saw a lot of cool architecture and had a really good lunch. Seeing how you are only visiting for a few days, you may want to focus on London only. Most of these days trips I took on my second/third trips to London.

One daytrip that might interest you however is Paris. If you wake up early, take the earliest train and the latest train back you can spend a day in Paris. When I did it, we had time to see the Eiffel tower, the Sacré-Cœur Basilica, do a river tour and see the louvre. Pretty pricy though, just warning you.

British Museum and the National Gallery. Both are free and the British History Museum has some crazy shit the brits have stolen over the years.

Nice 1 lol

Hamleys, Harrods, visit a good pub or two, sightseeing, Oxford Street, Westfield
etc

London Dungeon was kind of interesting and not super boring imo

As someone suggested, you can take day trips. If you consider it, I HIGHLY recommend going to see Cambridge. The town is beautiful and if you do the punting on the River Cam you get a tour of the whole University via a gondola type thing where you sit and get pushed around. You can even pack a nice picnic. I've done it many times and it was one of my favorite things to do in England.

Here's their pricing info if you're interested. It's relatively cheap and it's great fun.

After you do that, you should still have time to walk around and see the rest of the town and shops and such before you have to go back down to London.

Depends what you are after. I lived in London for 20 years or so,

Most of the national galleries and museums are free

If you're into the architecture, take a walk from the City of London (financial district for you Americans) at the weekend it's empty.

The London Eye is worth it for a birds eye view of London, I love it at sunset http://www.londoneye.com/
Or even the viewing platform at the Shard http://www.the-shard.com/

A boat trip along the Thames is good, there's 2 types of boats. Tourist boats or the River Bus. The
River bus is cheaper as you can use your Oyster Card. While I remember get an Oyster https://oyster.tfl.gov.uk/oyster/link/0005.do as it's the cheapest easiest way of getting around

Shoreditch is hipster central if you're into skinny jeans.

Soho is nice for a drink on summer evenings, stick to the pubs where everyone drinks out side.

The Southbank has quite a few restaurants and bars if you want to sit outside and people watch.

A note of caution, it's the school holidays so every where is pretty busy, it's worth booking somethings unless you want to spend time in a queue surrounded by over excited families

all of these are good suggestions

Obviously MnM's world is the place to go...

A trip up the London Eye at night is real nice.

If you're planning on going into a lot of the big touristy things then the london pass is worth it. I'm headed to london today with the gf until the boys arrive on tues & thats what we're planning (end up making your money's worth after like half the attractions entry fees)

camden is a fucking awesome and weird place to go, highly recommend it. London Eye is pretty good, science museum is awesome, buckingham palace, trafalgar square etc.

When I pass through to visit my parents sometimes I just walk around and shit, I really like the place and there's sooooo fucking many good places to eat.

I was just there as a tourist last month and I can tell you a few things I enjoyed

-British Museum. It's gigantic so you should try to explore as many exhibits as possible, or you could spend a full day there and try and see everything. It's free too and has cheap food for sale.
-Tate Modern. If you're into modern art this is the spot. It has like 5 galleries but it doesn't take ages to explore it all. They also have an awesome lawn on the shore of the Thames where you can chill and have a coffee. Free as well.
-The Globe. I would definitely recommend seeing a play. I'm not the biggest theater fan, but this place was really enjoyable. You can choose standing room only tickets, which are really cheap at 5 pounds, or seated tickets which are a bit more expensive.
-Pub crawl. These are super fun. I went on one that was called the rock and roll tour and I got to see all the places in London that are important to rock and roll history. I also went to two pubs. As an 18 year-old American, this was the highlight of the trip for me :)
-Parks. I spent a whole afternoon walking through Hyde Park and eating ice cream and enjoying the weather. It's basically London's central park, so don't expect to walk across it quickly.
-You should also buy an Oyster card, basically a transit smart card that you can use on the Tube and buses. It saves you some money and is more convenient than buying tickets every time.

Hope these tips give you some ideas.

the Royal Institute is awesome to have a look around if you're passing by (you would only have to visit there for a short amount of time)

If by rollers you mean you are specifically going to watch rollerblading, the South Bank skate spot is pretty damn famous if you're into that scene.

Now, there are obviously an overwhelming number of places to go for great food in London, but have a few cool recommendations:
Wahaca (South Bank stall/ Covent Garden restaurant) - Mexican street-food style (+ a tequila tasting menu!)
Flesh & Buns (Covent Garden) - Order your fluffy white dumpling buns empty, and pick a bunch of different meats to put in them. Tastes goddamn incredible. Also there's hentai as bathroom wallpaper if you guys are stereotypical TF2 nerds.
Belgo (Covent Garden, notice a theme here?) - Belgian-style food. Mussels and stews and dark flavours and really strong beers. Only been once myself but I remember it being really good.
Brick Lane (a street in East London) - The best place to go for a curry in London by popular opinion. Like dining out in India without the week-long illness.
Chinatown - if you wanna get ripped off as tourists and eat the same thing your local takeaway makes.
Wetherspoons (various) - because you want to experience what life is like for the British working class (cheap beer and microwaved meals)

Kate Middleton

Discard everything except your clothes and go to Brixton, then play real life DayZ with the Yardies.

And so it begins.

Don't know if anyone has recommended this yet, but the London Dungeons are really entertaining and (in my opinion) are worth the visit entirely.

Would also recommend visiting a West End show or going to the variety of restaurants that are offered, I have a favourite Mexican/South American upmarket place called Cantina LaRedo

Hope this helped :D

Though it's not a bad idea, they are there for 2 days. Oyster is primarily designed for people making single journeys I believed? If so, isn't it better and easier to just buy a travel card each day at £8.95? Yes Oyster has a charge cap but we are talking about £1.50 difference each day.

Good ideas there, the only thing I can add is the Shard (viewing platform now available), Piccadilly Circus etc.

Jump on a sight seeing bus if you want to get some fresh air though it will probably be raining :)

If you're around for the Notting Hill carnival, def go to that. I see it clashes with i52 tho...
Fuck that means i am gonna miss seeing i52 :/

Greenwich is nice, especially up towards the Royal Observatory (0.0 Longitude amirite) but it's somewhat out of the way of all the other cool stuff.

My bad. Go to Knightsbridge to car-watch as it's the season for wealthy tourists flashing cash.
