Vegan friendly recommendation?
How about Elephant Walk? It's classy, tasty food, and they have a good-sized vegan section on their menu... they're very accomodating to special diets. Both the Cambridge and Boston locations are lovely (there's one in Waltham too, but I haven't been).
well, it's not really fancy, and in a less-showy part of town, but the grasshopper restaurant in allston is VERY good. stricty vegitarian, but i'm sure vegan is a high priority as well. it's always packed, so you know it's tasty. even my meat-loving boyfriend liked it! it's also pretty moderately-priced with HUGE portions.
The Ethiopian cuisine at Addis Red Sea is quite vegan-friendly, pretty and romantic, a bargain by the standards of its neighborhood (the South End), fresh, tasty, and novel.
Asmara in Central Square is a few steps down in flavor, atmopshere, and price (and is Eritrean, not Ethiopian); in fairness, I have not been here in some years.
Both have lots of fine options for non-vegans, too.
