Located in the heart of Pioneer Square, Trattoria Mitchelli serves good, basic Italian food in a cozy spot with friendly, old-world atmosphere. A vintage wooden-topped lunch counter in a room with classic hexagonal tile floors is a popular after-work and late-night gathering spot, and the conversation is lively. You can't go wrong here with the fettuccine con pollo, pizza from the wood-fired oven, or the pasta of the week served with your choice of sauce. For a rich dessert, dig into a caramello, a creamy caramel with toasted walnuts and whipped cream. If you're a night owl, keep Mitchelli's in mind -- full meals are served until 4am Friday and Saturday nights, catering to the starving hordes who pour out of the area's many bars after last call.
