Had the buffet today and it was quite good. The curry was a bit mild but then it IS a buffet. The server assured me that the curry from the menu is available in differing heat levels and the proceeded to bring me a small copper pot fill with freshly made chili paste. That did the trick!
It is on a par with other Indian buffets in town but some of the offerings were standouts, the goat masala amoung them. The Naan was very good, toothful and with lots of garlic.
Service was pleasent, despite what some reviewers have said, and we were never wanting for anything. And not a single television to be seen! (This last is a major plus in my book.)
Overall I think you'll find the buffet at Guru Palace very enjoyable and you will be back again and again.
