Good Indian Food?
Madras Pavillion was my favorite until the trip last week. New favorite is in Plano and well worth the trip--The Curry Pot.-- Excellent lunch buffet. I'll have to try it for dinner but can't imagine it not being excellent. The spice and flavor were the best I've had.
Madras is vegetarian. The Curry Pot also serves meat dishes including fish and goat. (I did not try the goat but my brother liked it.)
I generally like India Palace. Not outstanding quality, but best overall in Dallas, although it's way too far north for my tastes. Roti Grill on McKinney just south of Knox, has a much paired down menu, but the quality is generally pretty good.
There is also a place that is way out by DFW airport in Irving called Pasand. I just happened upon it looking for some non-chain place to eat on the way to the airport one day before cell phone's could look up places to eat. Pretty good quality and I've eaten there a time or two when I've been early for a flight or a flight has been delayed. But it isn't good enough to warrant a drive that far out just to eat dinner.
There are also a fair number of reports that there are good Indian food restaurants out in the far out north suburbs like Richardson, Plano, etc. I never go out that far to eat, so I can't comment on any of those places.
