I'm going to the American Rep this Saturday evening and to dinner for my birthday. I have to decide among Upstairs on the Square, Sandrine's, Chez Henri. Also, is there a preference for either the upstairs or the downstairs at Upstairs on the Square? I value your opinions. I have never been to Sandrine's, Chez Henri or Upstairs at their new location. (I have decided against the Rialto and Henrietta's because I have been to both places on several occasions and want to try something new.) Thanks for your help.
