I love "The White Rabbit"! It serves classic European comfort food and favourites like Beef Bourginon, Crepes Suzette and much more. I especially adore the ambience of the restaurant, it is a set in a restored chapel and there's something about the feel of The White Rabbit that makes me feel like I'm Alice in Wonderland :) It's a bit pricey but for a special date night, I reckon it's worth it.
Jim Thompson is great for thai food, ps cafe for international, prime society for steaks...
Chopsuey café, very nice, good food and reasonable prices!
