I recently tried the gua bao from Andy's in Rego Park and it was AMAZING. The bread was so soft and fluffy, and the pork was so rich, meaty and flavorful. Yum. Way better than Momofuku's pork buns, plus the rest of the menu is pretty good, too. Delivery is also speedy on most nights. Just a note: It's listed as a "Taiwanese hamburger" on the menu.
