I have been eating at Le Querce regularly since moving here seven years ago and it's my favourite restaurant. The owners now know us and we've always found them friendly and very nice.
One new year (2008/9?) we had the multi-course tasting menu and it was one of the best meals I've ever eaten - fatty tuna (better than it sounds), tagliatelle in brodo, seafood dishes etc. It wasn't cheap but well worth it.
I don't get why people moan about the interior. I think it looks lovely, with the brightly coloured walls and artwork.
If/when we eventually move away from the area this will be the main business we miss, by a very great margin, and it's a place I'd happily travel to from other parts of London.
Other places locally - I like the Babur, but find it noisy and it tends to attract large parties, and their relentless marketing techniques are a bit much...
Gone right off Donde - I used to like it but the service the last few times we have been has been Fawlty Towers and we've had to send food back (pink inside, half frozen white fish, anyone?). It also has a distinctive smell I don't like.
Love The Gantry. The one time I ate at Stone Bar it was very good, but it is bit clubby for just eating (we were at a birthday). Miss Tai Wu, and miss having a decent Thai restaurant (the ones on Gellatly Road and Brockley Road are not decent), though I have heard there's a good Thai café in Brockley.
