Can't believe that I haven't made it in there before now but wow, very huge nice market for international cooking. I wish I knew how to use all the stuff in there but I'm going to start learning. Fabulous seafood section with live fish in a tank (might have talapia ?). Excellent produce and loads of isles of exciting everything. Check it out. It's called "Battambang Market" on Church St. in the plaza - this link says Merrimack St. - that's incorrect.
I was raving at the register and one of the employees says it's the largest north of Boston.
