Resto 65 Yori, Piccadilly
For about 12 quid for food and beer Yori offers good value if you don't want to spend too much but feel like going somewheret superior to a chain place for lunch.
Review #79 Bibigo, Islington
Bibigo makes for a very civilised evening out that won't break the bank.
Review #71 Bi Won, Bloomsbury
Good value Korean around the corner from the BM ... I also recommend their Sunken Cities exhibition.
