There was something about Il Posto that moved us on our very first meal there. It wasn't the food, and it certainly wasn't the staff. No, it was something about the vibe — some indefinable hum of friction between the kitchen and the floor, the customers and the chalkboard menus hung high on the walls, that just made the place seem alive. And since it opened three years ago, the food has improved markedly, the staff has mellowed, the early crush of neighborhood trend-humpers trying to squeeze through the door on a Saturday night has cooled, but that vibe remains — that feeling of excitement that the best neighborhood restaurants must have, regardless of their price point.
