This is by far my favorite restaurant in Pgh, and the best food I've found anywhere in the world - honestly. Sometimes, I'll eat there 2ce a day.
Not only is it the best tasting food, it's also the best price in town - $4 lunch or $5 dinner for enough food to fill you up, maybe with leftovers.
Monday and Friday are my favorite days - he has Chickpea Potato, Masala Tofu, and Tomato Dal. It's to die for.
Sorry to hear about Grace's bad experience. The earlier you get there, the better the food is, no doubt, but I've been eating Sree's for 4 years and I've never gotten sick. Maybe their stomachs just weren't ready for Hyderabadi food? I remember, when I first started eating there, I thought it was the spiciest thing I'd ever tasted. Now it tastes just perfect, so it might take a few meals to get your digestive track used to the spices.
