Experience was diminished because of extreme noise level and crowded dining room. Tables packed in too tightly. Food and service were excellent but totally enjoyable because of the environment.

It was 6:45 PM on a Saturday evening on a beautiful day in the city. The restaurant was packed inside and out. We will probably be oldest patrons by far. The drinks were terrific, the appetizers and oysters were fresh and beautifully served. The mussels were as good as you could get. If you really want to splurge get the donut assortment for dessert. They were outrageous! I would highly recommend for those who would like to have this type of food.

Family-owned Flex Mussels always provides an exceptional dining experience, with attentive service and a terrific atmosphere. Don't miss the mussels (duh), raw oysters, lobster roll, Filet o' Flex and so much more!

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.
