Went to Benares in Mayfair a couple of weeks ago, absolutely amazing food and the service was superb, attentive but not intrusive. Best restaurant experience I've ever had.
Namh, supposedly the only Michelin starred Thai restaurant, in the Belkin Hotel is also worth visiting. Intense flavours and taste combinations that are like but unlike usual Thai restaurants. Difficult to explain but an amazing experience. Over fussy waiters though.http://halkin.como.bz/default.asp?section=186
Tamarind - another posh Indian in Mayfair but went on the Toptable sunday lunch 2-4-1 offer which is still running (Taster Menu 2-4-1). Again an experience that is highly recommended.
Planet Spice - modern Indian in Croydon. If this place was more central it would cost £££. Absolutely superb and pretty reasonable (c£35 a head) for the quality of the food and the service.
Shilpa - King Street, Hammersmith. Really nice South Indian restaurant. Well worth a look if you're sick and tired of the usual jalfrezi/korma/rogan josh fare served up in curry houses. Offers often on Toptable, woth a punt for £20 per head.
Anatolia Ocakbasi - Mare Street, Hackney. Great value Turkish restaurant on corner of road of Carhartt Warehouse store (that now seems to be selling Fred Perry, Edwin, Tonite and Folk amongst others)
Mahdi - King Street, Hammersmith. Reasonably priced Persian restaurant. Lots of grilled, flavoursome meat and the nan bread is amazing, huge, thin and crispy. About £12 a head.
Thai Square - a chain but the food is good. Have eaten in the Sevenoaks and Windsor branches and never been disappointed. I was always put off but it being a chain, thinking it was going to be a bit mediocre but have not been disappointed.
If any Fuker is ever in Sydney, Lees Fortuna Court in Crows Nest is the daddy of restaurants. Great food and service.
