The tables are filled with them: lone gnawers, grazers, and nibblers fiddling with cell phones, flipping through newspapers, or fumbling with Palm Pilots. With so many solo gourmandes taking down plates of Caesar salad, soups, sandwiches, rotisserie chicken, and daily specials (all obtained cafeteria-style so you don't have to feel like a lonely shmuck while a server takes your order with one of those ridiculing gazes), no one will notice you. Which, for once, is just what you want.
