5 of us in NY for a girls weekend in June. Staying on the Upper East Side and got a recommendation for Sette Mezzo for Friday night. Read somewhere that staff isn't friendly if you're not a regular--would love to hear fellow Chowhounds' experiences. Also looking for a moderately-priced restaurant near Lincoln Center for post-concert dining Saturday night. Lively atmosphere with good food and reasonably-priced wine list. Considering Nick & Toni's or Picholine--any comments or other suggestions?
