I've been to Dumplings and Things a couple of times now and I give it a big thumbs up. Solid food, great variety of little dishes, great prices and the people are really nice.
The dumplings aren't the best I've ever had, but they're the best in the neighborhood. They have a small menu with a nice variety of other offerings. The cold noodles with sesame sauce were a real standout for me. Dark noodles, served cold (instead of room temperature) and a tasty, thin sauce. I've also had the pork belly buns which were fantastic.
I've always left stuffed and happy for under $10; including a drink.
They're on Fifth Ave between 5th and 6th Streets. Unfortunately, they don't deliver yet.
