Twofer trying to decide about Saturday night in Cambridge, with an inclination toward some place within walking distance of Havard Square. Been to Rialto, Sandrine, and Craigie Street.Looking for something else to thrill the foodie. Ruled out Harvest. What about Upstairs on the Square (downstairs) or Tamarind? Elephant Walk on Mass Ave? EVOO? Aspasia? Chez Henri? Help!
