I'm having a Moules Marinieres craving, and need to buy mussels. I've bought most recently at WF (River street) and they were lousy- It was good that I bought two bags, because over 50% were already opened and therefore probably not safe to eat (according to conventional wisdom).
The ones that were edible were small and somewhat stringy, not plump and succulent.
Any suggestions on a better place to buy them? I work in Boston, live in Cambridge, extra points if it's open until 6:30/ 7 so I can get there tonight, although for the perfect mussels I could wait and make a field trip tomorrow.
