The first idea that pops into your head when you think of a place to eat in Camden Town are the places in the market. Surely, the second option you think are the food stalls as well!
Well, if you want to look for a third option, here's a winning bet: Market Restaurant. It's located about five minutes from the tube stop (in the opposite direction from the market) and offers a taste of modern British cuisine, creative and very elegant. The menu is not too long, but that doesn't matter, the emphasis here is on good ingredients. With good products, a classic recipe, and a twist, the dish being served have all the ingredients for success. The place is very nice and the waiters are really efficient. Additionally, the top floor has a small group room (discounted rates, of course). As far as price is concerned, it is quite affordable (considering the quality of food): main courses are around 15 pounds, beer 4.5 pounds, and desserts between 5 and 7 pounds. Of course, you also have to add a 12.5% tip. Try to get a table next to the window and relax, have some well-prepared food, sip the beer of your choice (they have some excellent ones) and just watch the colorful neighborhood of Camden. A show like none other :)
The River Lounge is a restaurant on the St Katharine Docks, not too far from the Tower Bridge. When guests come visit me in London I like to start with a visit to the banks of the Thames, ending at noon at the Tower Bridge and eating in one of the neighborhood restaurants. The river lounge has a warm wooden construction and looks over the little St. Katharine docks. It is a rather exclusive, but since the currency is weaker now, it doesn't seem as expensive. It's open every day until 11pm except Sundays when they close at 7pm. The menu has a mix of European and English dishes that range between 7 to 15 pounds.
The website does not appear in many guides and, despite its claims, not many people know about it. Tower 42, once the ceiling of London (gray tower in the City by the ubiquitous "Gherkin") has, on the top floor, a restaurant/cocktail bar. Tables are set by windows that go from floor to ceiling. The views, mostly to the south/west are spectacular, especially at sunset. The food is nothing special and of course is expensive. But the cocktails (for London) are reasonably priced and with the bonus of the view become good value. It has a somewhat restricted schedule and booking is advisable.
At this restaurant I had the chance to eat the London Tower Hamburger, I remember that name. It was huge but mostly, meat and other ingredients were of high quality, nothing to do with conventional burgers. I have good memories of that place of truth. I know there are many sites where you put burgers great, but with this quality I have not tried another.
This nice restaurant is hidden in the narrow streets of Mayfair. Eating in a restaurant in London is expensive, and most expensive in a good restaurant. In this restaurant, they have a tasting menu for 80 GBP (drinks not included) which allows you to taste five courses and dessert. All the meals are exquisite, beautifully presented and served nicely. The service is fabulous: The waiters, who all have strong French accents, make sure you're comfortable.
I know it's a chain, but it's right outside of the Notting Hill tube station and I couldn't resist. It was your typical rainy cold London day and the cozy, warm interior was calling me! It was a great choice. We got a soup, hummus, a good beer, some tea, and dessert. My companion ordered a delicious steak and mushroom pie that he said was very tasty. A tad more expensive than I expected, though. €51.00 for two people.
