missed your post for today, but a good place to have lunch outside is Jardin du Roi in Chappaqua. The sandwiches in particular are very good - I love the merguez sandwich. Also the mozarella and prosciutto is good.
The Lex & Tuscan Oven in Mount Kisco. Brio (used to be John's Worst Pizza) is good too, though a bit noisy from 117. Deer Park in Katonah (rt. 35 & 22). La Fontaine in Somers (Rt 100 north of PepsiCo) and Baccio in Cross River (Rt 35 and 121, owned by the same people)
