Good, but expensive for what it is.
The selection of literally dozens of different kids of mussels is dizzying. The only thing even more impressive is the enormous beer menu, featuring everything from Belgian trappist ales to local microbrew specialties. The burgers and other food items are creative and tasty, and the portion sizes are reasonable without being stingy. I also enjoy the atmosphere of this restaurant in the summertime, though it should be avoided on the busy Thursday and Friday nights.
The reason I only give it three stars is because everything is way overpriced for the area and for the type of food. You could eat just as well for half the price just about anywhere else nearby. If I wanted to splurge and spend $50 on a meal, I'd expect something much nicer and fancier than this. But for a burger and a beer, or even the all-you-can-eat mussels specials, the price is just astronomical.
