I'm amazed and thrilled that a place has a Friday and Saturday night buffet, and such a good one. It is the best vegetarian buffet in the Cities.
As other reviewers have noted, everything is clearly marked if it's vegan, and unmarked if it's vegetarian. This includes the menu (starred) as well as the buffet signs ("vegan"). (If it were this easy to go vegan, I would be one!)
Overall, I've had very good experiences with both the food and the service. However, the ambiance varies according to where you're seated. Sometimes it feels like a four-square remodeled shoe box, at other times, it feels warm and intimate.
I have yet to decide for sure whether I like The Vegetarian or Mysore more when it comes to Indian food, but I'm very glad that Mysore is around, in any case.
(Update 11/24/07: Mysore is no longer "all vegitarian" (sic) (as all of their signs and menus read). They're serving chicken in their buffet, "because we were losing business", according to one of the managers. This comes, of course, at the expense of the variety of vegan and vegetarian choices. I guess that makes the decision between The Vegetarian and Mysore that much easier. Minus one star to Mysore.)
(I feel like going on a mini-rant here. How can one infer that the lack of chicken on a menu would equate to losing business? Or: how would false advertising and possibly alienating your core group of customers expect to increase business?)
