Ok so I lived in Cambridge for several years and I work in Harvard Square but I'm having a hard time thinking of a place to eat. This Saturday my mother, 2 aunts, and grandmother are coming to visit. They're staying just across the river from Harvard Square near Harvard Business School. They probably won't get here til around 7 p.m. and they'll be hungry. We've done the Legal thing several times and I'm trying to think of somewhere in Harvard Square that won't be way too crowded or noisy (Grandma is 84 and getting hard of hearing)... My aunt won't eat anything "strange" so Chinese, Thai, etc. are out... Some place basic.. I thought Grafton or Red Line but I'm sure they'll be packed.. Any other ideas????
