If you like indian food, I recommend Annalakshmi in Brickfields, beside the Temple of Fine Arts.

Weekends they do buffet, rm18 per person, large variety of dishes to choose from plus chapati, naan and/or puri made to order.

Food is top class, but service can be a bit slow, partly because the service staff are volunteers and the place is run as charity for the Temple of Fine Arts.
