I've recently been to
GIZLI at Wandsworth Bridge Road, London.
Very decent Turkish cuisine. Very quiet place, professional staff (is it racist to say that politeness and professionalism is a rare thing in Turkish restaurants? or is it just me?). Great shish kebab, big generous portions, served beautifully, the meat is fresh. It's a family place, and the owner's wife is the cook, I think. She knows her stuff, , and the guy does the desserts. Highly recommend for their meat.
The other one I would recommend is probably
L'oro di Napoli at Uxbridge Road, Hanwell W7 3TH.
It's a pizza place, Itlian. Neapolitan, to be precise. They have a wonderful selection of pizzas, amazing meatlballs, salads and bread. The staff are well-schooled, and the food is fresh and cheap, so I would definetely say it's worth the money. The only problem is finding it and parking near it. I think it's good for families and singles alike, very calm and comfortable Italian restaurant.
