Le Bureau is a good spot to get together with friends for drinks. We visited on Saturday night and the atmosphere was relaxed, the bar got full around 8pm, but we still could hear each other. Although the web site states they don't take reservations for less then ten people, they actually accepted mine for eight, which was really great.
Food wise I would't say that very high requirements will be necessarily satisfied. The tapas are of good size and are quite delicious, but not as elaborate or outstanding as to make foodies happy. However, everything we had was memorable and filling: the hummus with the warm naan bread may suffice if somebody is looking for something to snack on, the gravlax is also a nice choice and the salmon comes on a bed of fennel salad. The grilled veggies and the rib of my friends looked very attractive.
The drinks menu is extensive, particularly the cocktail list. I loved our cozy table at the back of the pub. Overall I would rate this place as four stars on my special scale of six and I would be definitely back.
