On the other hand...the Buffet Maharajah is hands down one of the half dozen worst restaurants I've eaten at in my whole life. For some strange reason, I went there twice with my family. I, personally, couldn't eat much of their greasy garbage, but my daughter both times left the place sick.I've tried a lot of Indian restaurant in different countries, especially in London andeven in India. When it comes to Indian restaurant (with buffet) in Montreal I canr ecommend Buffet Maharajah

I know that there's a lot of Indian buffet in Park extension (on Jean-Talon Street) or even a little bit up North on Jarry. I've never try one of these joints; for that reason I cannot vouch for them.
To sum it up: a good location downton with a buffet : Maharajah.
I'll agree with you, however, that the Indian places on Jean-Talon West are quite good. The best Indian restaurant on the island, in my experience, is Bombay Choupati in Pierrefonds. Get there early, though; they don't take reservations and there's often a line. Another good one is Malhi Sweets at 800 Jarry West.
As is almost always the case, if you want to eat well in Montreal, you must first get out of the downtown area or pay excessive prices for less than the best.
