So my family is coming into town for my college graduation, and I'm supposed to pick a location for a celebratory dinner. My tastes lean toward eclectic and ethnic, but my grandmother's coming and hers... don't. SO, I need a fancy, classy place for an excellent dinner (we're real foodies) preferrably in Boston/Cambridge. Price is effectively not an issue, but it should be relatively mainstream so Grandma can get her standard, boring food even at extreme prices.
Any recommendations? thanks in advance!
