I recently finished writing a new page on Boston's Hidden Restaurants on cheap eats in Boston, and, while I geared this page toward college students in Boston, some of the restaurants are perfect for anyone looking for a good meal but not looking to spend too much.
A few that stand out are India Quality in Kenmore Square, a terrific Indian restaurant with very friendly people working there; Dok Bua in Brookline, possibly the best Thai restaurant in the Boston area; Mr. Bartley's Burger Cottage, a famous hamburger joint near Harvard University; and Cafe Jaffa, an outstanding Middle Eastern restaurant in the Back Bay.
If anyone has any other places that I could include on the page, let me know. Thanks!
