Dined here earlier this week and had a lovely time. Arrived during the transition between lunch and dinner so had limited menu options but it was fine. What was available was delicious. I liked that alternative options to mussels in white wine sauce were listed, that was a nice change. This version of mussels had a nice kick. Bread had to be requested, it wasn’t included which was fine. Just could let all that yummy broth the mussels were sitting in go to waste. I’m a bit particular with French fries and these were perfect. I recommend checking this place out. Perfect for solo eating, a date, yap session with friends, etc. I’m not on the UES often but I definitely want to come back and try more of their menu.

It seemed like a hidden gem I stumbled upon by chance, yet clearly a local favourite. The mussel dish had no unpleasant smell, and the Wagyu burger—if I recall correctly—was bursting with juicy flavour as I cut it in half; it truly tasted as good as it looked. The male staff member provided impeccable service and appeared to be a person of great tact and charm. Although the ambience and interior design left something to be desired, the quality of the food more than made up for it. I intend to return next week for another visit.

For many years I have enjoyed everything they have to offer, whether it’s their happy hour specials, some delicious dessert donuts, or a big pot of mussels. Last night they blew us away with their summer lobster special that our whole family enjoyed. Such a treat!

Where do I start?! My experience from beginning to end was nothing short of amazing. It was the highlight of my day. Curtis and the staff really went above and beyond to give us the best experience. Very attentive! I didn’t have to call anyone for anything. They were so on top of it making sure our drinks were always filled, the bread was always filled and making sure we were enjoying everything. Now the food, wow. I couldn’t stop talking about how good everything tasted while I was eating. The Bangkok Mussels Pot special was so good, I went to sleep thinking about it. My friend tried the Parma and it was so tasty. We also got the Red Snapper ceviche and my goodness, so tasty!! The Parmesan truffle fries with that aioli was to dieeeee for 🤤 our drinks we so yummy we definitely repeated! The doughnuts, oh my goodness. Those were probably the best I’ve ever had. They were so fluffy and each one was different. 100/10. Very happy with my experience! Thank you!

Tried Flex Mussels for the first time and the vibe was absolutely spot on—inviting, lively, and the perfect setting for a seafood feast. We kicked things off with a solid lineup: fresh oysters, a flavorful fish dip, perfectly crispy calamari, and a side of fries to get things rolling. The star of the show? The mussels. Each sauce was bold, rich, and packed with flavor—perfect for soaking up with the bread, which honestly became its own highlight. We also sampled the fish sandwich and some burgers, all of which were cooked just right and left us wanting more (so naturally, we ordered more fries). To top it all off, we wrapped the meal with fresh, warm donuts that sealed the deal. Service was on point—our waiter was friendly, attentive, and knew the menu inside out. All around, an incredible food experience with great energy and even better flavors. Definitely looking forward to going back.

What should you keep in mind when planning a meetup at Flex Mussels?

The restaurant’s lively yet comfortable atmosphere is ideal for socializing, but if your group prefers quieter settings, timing your visit earlier in the evening or on weekdays may be beneficial.
