HK food court is good, directly across from Nancy's
81st street and Roosevelt has a bodega on the corner. If you go in the back of the Bodega, they sell tacos, so far best in NYC for me(last time I was there was almost 9 months ago).
Skillman and 52nd street, one block from 51-19 relax spa. There is a fusion Tibbetan place named Dawa, the most unique and one of a kind food in Queens. However, this place is crawled with couple and family. It is awkward to eat alone here.
