Here are some pictures from Super 88, Boston's Asian mega-market. Good pan-Asian grocery selection, organized by region. Clean, and cheap-- on par with the Asian markets here, price-wise. Super-duper-impressive seafood selection; you can see tanks of live fish below the fish counter in the last pic. They seemed to have a half dozen fishmongers on active duty there. It is a mini-chain in Boston (there are, I think, six); I went to the one in the South Bay Center, off 93.
