I'm going to travel in Boston this summer with my family (4 people); therefore, I would like your kindly recommendation about inexpensive restaurants in Boston area.
Any kind of food but not more than $10 - $15 per dish if possible or any suggestion about family set would be wonderful. Just tasting OK, not bad. I will visit here for 4 days, and I stay near Harvard Square. We don't have a car, so any restaurant near subway would be great.
Note: I did search for some informations already, but it had no clues about prices.
