My parents are visiting me here in Boston in early July. Coming from suburban Ohio with travel limited to North America, their experience with unique (particularly ethnic) cuisines is seriously limited. (Mediocre sushi a few years back was a relevation for my father. Oh god, and he had no idea what this strange thing in a tin, fois gras, was that I brought back from Paris.) As a result, I make it my mission to introduce them to food they would otherwise never experience.
So, I'm looking for recs of restaurants with cuisine that will be new and exciting for my Ohioian parents. It can be anywhere in Boston or Cambridge, and I'd like to keep the price reasonable, if not on the middle to low end. I had thought of taking them to Addis Red Sea for some Ethiopian, but I've already been, and selfishly, because I'm relatively new to Boston, I wanted to head somewhere new for all of us. (Also, I've already taken my mom to Toro so that's out. And yes, some items on the menu were a bit too extreme for her!) I was thinking of maybe one of the Portuguese places in Cambridge or Helmand for Afghani? Thoughts on those? Ideas of others?
One final requirement, I'm a bit of a health nut and while it's not a definite prerequisite, healthier cuisine, or at least healthier options, would be much preferred. Additionally, I typically don't eat meat, though I do eat fish/shellfish. Restaurants heavy on meat, lacking on seafood/vegs would probably not be too high on my list. Ok well, I hope this isn't too much to ask! I REALLY appreciate any help on this you can give me! Thanks in advance!!
