    The host seated us upstairs even though there were plenty of tables downstairs and he wanted to squeeze us between tables . We declined and went downstairs. Our waiter Curtis was very friendly and helpful. Portion sizes not great for price point. Thai mussels were absolutely delicious.

    The bar was a bit disappointing - avg drinks and $13 for a mocktail was too much! Saving grace are the mussels and frites. Huge mussels and oh so tasty. Should have skipped the lobster roll. Excellent staff.

    We had an amazing experience at flex mussels! We ordered the scampi, lobster roll, truffle fries and had brownie as a dessert. Our server Janelle was really sweet, nice and helpful. The restaurant is pretty crowded though and it’s very noisy inside, so we decided to sit outside. They do have heaters, but it wasn’t as warm as inside - so it’s up to you! I felt a little bit cold in the end. Overall, it was a nice experience and will be back to try the Diavolo mussels!
