I'm visiting your very pretty city from San Francisco, where I usually post and review restaurants. Now I am visiting Boston (Tuesday, Wednesday and Thursday) and would love some recommendation for a quintessential Boston experience. Anything that is local and typical is fair game- and ethnic restaurants are not, unless you feel they are a must experience (I'm thinking he equivalent of Momofuku in New York!). I am also looking for a restaurant recommendation for the North End without ending up at a tourist trap. Help??
