I stopped by a new Tibetan fast food place this weekend. Unfortunately, I did not record the name of the restaurant, but it's located on that short block where the Indian movie theater and subway entrance is.
They had both chaat and Tibetan food, probably more chaat then Tibetan. I'm not sure why. On the counter was a Chai dispenser and a thermos. The thermos was corked and had Tibetan-style salted tea inside. Both types of tea were good. I'm assuming they were free, but maybe I was charged for it. It was all very informal.
As far as I can tell, the Tibetan food you can get are all dumplings: beef, chicken or vegetarian. I tried the beef. The dumplings were steamed, I believe. The dumpling skin was light and too delicate, but the beef inside was pleasantly greasy and tasty. It came with a Tibetan hot sauce that was quite nice.
Dumplings were about $6.50 total, and the staff was very pleasant. If you are in Jackson Heights, and want a meaty snack, this is a pretty good way to go. It suited the cold, snowy weather perfectly.
