Glad to see this thread is getting some recent responses. Here's some of what I've had since late 2005:
Rezas- definitely a great meal there. Lots to choose from and the times I've gone there was quite a few people.... meaning good quick turnover of food.
Sushi Para Too - Not exactly the best sushi I've ever had, but for some decent and plentiful sushi (as much as you can stuff yourself with) at $14, I'd definitely return. What I also enjoyed was the option of all you can eat non sushi items such as gyoza, shumai, salad, etc.
Indian Grill - A couple of doors down (literally) from Sushi Para Too, this place is a good primer to Indian food. The owner has always been insightful of the buffet offerings when I brought friends new to Indian cuisine.
Mt. Everest (Evanston) - This place offers a great lunch buffet, one my husband favors over many other we've tried. I especially like their tandooi chicken, which has been done very well with moist and juicy results. Other places I've been often have slightly tough and dry tandoori chicken.
Garden Buffet on Lincoln - As many others have already commented, this is a good place for Korean BBQ. The offerings are good - with or without the BBQ option - and from the times I've dined there, they are very clean. The only downfall is the florescent lighting.
I'm headed out to Red Apple on Milwaukee later this month with my cooking group... and I'm excited to try some Polish eats. Thanks for the previous recs on Red Apple!
