We have a pretty good variety of Cambodian food in the area. Probably my favorite is Thmor Dat on Shirley Ave. in Revere. It's just a Chinatown storefront with food cooked by Cambodians. and most of their customers are Cambodian...ez access by the Blue Line. This is the first place I had cambodian and it's said that you never forget your first time..:) byo
Mittaheap in Lynn is very good but hard for me to get to..more extensive menu.
Floating Rock in Cambridge...This was the original Thmor Dat. It's much more upscale and on my 2 trips, I wasn't able to get the "real" thing...seemed a little dumbed down. Nice space..full liquor.
Lowell has a # of good places but someone else will have to brief you on those. I'm just not familiar with specifics.
