Say you moved from downtown to the Upper East Side, and the main thing you miss about lower Manhattan is the abundance of dumplings. In that case, you’ll want to know about Tri Dim Shanghai. It isn’t anything especially fancy or remarkable, but the menu is big, it’s affordable, and it’s both nice enough for a dinner with your parents and casual enough for some takeout on the way home from the gym. There are a bunch of big round tables, so feel free to come with a group, and be sure to get some soup dumplings.
