About ten days before I ate the moules et frites at jacs, I ate the same meal less than a football field from the sea in France. My husband and I had the same reaction to the mussels at jacs- they were, hands down, much better than the ones I'd had ten days earlier.
We also shared the crab cake appetizer, which was the perfect size for two people to split, and was nice and light with plenty of crab flavor coming through instead of too much filler. My husband had the special that night, which was a pork medallion and chipotle mashed potato, and while he doesn't usually enjoy mashed potatoes, he found them delicious.
Great experience at jacs, would definitely recommend for a nice dinner out or for a mellow place to take visiting in-laws and the like.
