I like the Cafe Bombay
off of North Druid Hills. They have belly dancers on the weekends, and the food is great.
A little cheaper, and on the other side of town (Decatur) is Zyka.
This is a great place for lunch. It's in an old school and it's not the most impressive looking dining room. Then they hand you this AWESOME food on a cheapass styrofoam plate. I highly recommend Zyka.
