We live in NDG and always order our Indian food from this place. I've eaten there a few times for the buffet (totally worth the cost). Fresh, fabulous, great service.
As for delivery - they have a huge menu with something for everybody and it gets to you fast.
I've been to their competition across the street (Ganges) which is also good but this place seems a little more relaxed and the food is always terrific.
You should go!
