Viand Coffee Shop, a diner at Madison and 61st, makes a terrific tomato and feta omelet, one of the best that prima—an aficionado of the Greek omelet—has ever had. This is the oldest of several Viands around town; it's also gotten buzz for its freshly roasted turkey sandwiches. "Good people watching, too," prima notes.
