A couple of times a week I find I am in and around London looking for an interesting bite for lunch. Many of my destinations have been culled from Chowhound in the past. My list is below (only the really outstanding) but I will be grateful for any more suggestions.
Mama Lan - good dumplings and on my last visit a stand-out spicy beef and noodle soup
Franco Manca pizza
Case Morita - excellent tacos and quesadillas
Foxlow - Chicken Salsa sandwich (was off menu but I imagine it will get there one day)
Brick wood Cafe - the absolutely best toasted cheese sandwich and a very fine flat white - becoming a bad habit
