Any thoughts on Sukhaida
If you mean Sukhadia's on 45th, I like it a lot. There is the sweet shop in the front and food food in the back. Not too pricey, tasted pretty authentic to me--I spent three weeks in India. I went for the buffet lunch on a weekend and everyone there was Indian. [One problem was that I went late and since it was buffet, the food was kind of running out. So find out the hours and go more toward the beginning. The chai is really delicious.] My Indian friend had her brother's engagement party there and they all LOVED the food.
I have never been to India, but I have had Sukhadia's buffet lunch, chaat; and the sweets--all really good, though I am particularly fond of the sweets.
I have found that the people who work by the sweet counter are very nice about givig out samples, to help you make a decision.
