I'm hoping to buy a couple of bento box trays (empty) to give as gifts to my folks, who have recently discovered the joy of homemade sushi. I haven't looked specifically at Super 88 (Comm Ave in Boston or the one on Hancock St in Quincy are most convenient fo rme) or Kam Man Marketplace in Quincy, but these are the places I'd be most likely to start my search. Can anyone shorten my search for me by telling me if you've seen these in the cookware sections there? I've mostly stuck to the food aisles and haven't really browsed the cookware sections. And if not there, anywhere else in Boston? Thanks a mil.
