Bombay Bistro downtown Minneapolis
As starting points, here is what the search function turned up:
The quick summary is that there are recommendations for the lunch buffet. There are two locations, nearly adjacent, that serve different menus; the one in the Medical Arts building seems to be preferred.
In my opinion, it's fine, but not great. We were there for dinner one night. Nice atmosphere, service was middling. Fairly good spice blends, and nice fry jobs on the pakoras and samosas, but nothing that really blew us away. There are a lot of places in the Cities that do a decent, but not great, job with Indian, and this is one of them. It's not as good as Gandhi Mahal, in my opinion.
That said, it may be your best bet in downtown (definitely better than Dancing Ganesha), though I've heard great things about Copper Pot, if you're willing to go further. Haven't been there myself, but the rumors are that it's really strong.
