Looking for a true Chowhound place for this Saturday in Cambridge/Somerville. Have friends coming from Philadelphia for the w/e. Looking primarily for good food, ambience is a distant second. Cambridge/somerville was selected by a second local couple because they don't want to deal with parking in Boston (I haven't found cambridge to be much better, but at least it restricts the possibilities). I was considering EVOO and East Coast Grille although I have not yet been to either. I have one friend who was EXTREMELY dissapointed with EVOO but it is on the list due to a number of positive reviews here (primarily for the tasting menu, I believe). Our local friends suggested Salts, another restaurant that I know nothing about. It will be dinner for six, at 8:30 or later (after the kids are asleep). Any suggestions or guidance would be much appreciated.
