Fat dumpling is getting two stars because of its lack of customer service and so-so food. Dumplings look and tastes like they're hand made and fresh which is a plus, but it's also one of the only things that should be ordered there with the exception of appetizers and boba drinks.
My friends and I show up there with a party of 10 and asked if we could be seated together, so they told us that we could add two extra chairs to a table meant for 8. The tables are small so that wasn't going to work out. We suggested to add an additional table to accommodate us and their response to us was "We're going to be busy today, we can't do that." What???
We were all hungry and didn't want to fuss so we sat at different tables. We ordered beef and chicken pho, bun bo hue, pot stickers, pork and shrimp chive dumplings, pork cabbage dumplings, "pork steam bun"- really it was shanghai style dumplings, and chicken wings. Our dumplings came first and 30 mins later the noodle soups. By the time we received the noodle soups everyone that ordered the dumplings were already finished eating. Once everyone was sated they then decided to bring us the pot stickers that they forgot. They add gratuity so we no choice but to tip them.
