Heading up to Boston next week, have to figure out dinner Tuesday night. Staying on South Common; anywhere near there or Hanover St./North End (thinking of going to improv show there afterward). Read the incredibly helpful Boston Guide post from opinionatedchef and that has got breakfast and lunch (and the key gelato break) sorted but would love recs for a place in above areas that's got some authentic Boston flavor but not hushed or sceney or super-pricy. Kids are 5 & 8 not too adventurous nor picky (don't need kids' menu & crayons, but hey everybody like crayons esp. me). American/Seafood/Italian best. Also 6 pm on a Tuesday shouldn't be too hectic, yeah? Or go earlier? Thanks!
