The closest you can get to Little Italy in the east.
The owners are amazing, the atmosphere is relaxed, the lunches are abundant and homemade.
The cakes are amazing, try Torta Clara (pear and chocolate) for the ultimate bliss.
I've only just discovered this fantastic little salad bar-come-florist right round corner from my studio. It serves freshly made salads that are not only delicious but cheap too! Either take away, or grab the one and only table and eat in.
Zédel is my absolute favorite restaurant in London. Beside the fact that I love french cuisine, Zédel is aesthetically pleasing, very reasonably priced, is good for any occasion, and of course - delicious. My favorite is the bouillabaisse and a bottle of the Bordeaux Superior.
