My husband and I always end up going out Friday nights, but never make advance reservations because we don't know what time we'll be done with work. As a result, we've fallen into a rut of going to the same restaurants we know we can get a last-minute table at anywhere from 7 to 9:30 pm. Our current faves include Five Points and North Square. Sometimes we go to Deborah in the West Village or Le Zinc in Tribeca. So that's the price range, and general feel of what we're looking for, and it's a big plus if they serve a decent martini. Any suggestions for expanding our horizons? Thanks!
