Review summary

Flex Mussels on the Upper East Side is a "fabulous neighborhood spot" known for its "delicious mussels and great ambiance." Diners rave about the "fresh and delicious oysters" and the "fantastic" service. The "Thai mussels" and "everything donuts" are highly recommended. Despite some noise complaints, the outdoor seating offers a quieter option.

The food and service here are amazing. It’s a bit noisy inside, so if you are looking for a quieter experience, I recommend outside.

We absolutely love flex mussels! My family and I have been going there for years. We went last night to celebrate our daughter‘s graduation and while the food was delicious, we were absolutely freezing the entire meal. We asked if the AC could be turned down a bit as it was blowing heavily on us. We asked multiple times and ended up having to put napkins over our shoulders to try to warm up. The table next to us was freezing as well. It wasn’t even that cold outside! It really took away from the whole experience, the food got cold quickly, and it was beyond uncomfortable.
