[London Area] Off piste food with good wine
If wine is the main factor you need to go to The Wine Library. It's near Tower Hill tube station:
Lots of great wine to take away from the shop, or you can take it into the eating bit and drink it with their buffet food. Only bread, cheese, pate etc. but very good quality. The good bit is they only add £4.50 to the wine price if you do this, rather than almost trebling it like most restaurants have to. Thus a £15 bottle ends up costing you £20 rather than £40.
Some serious wines too.
