I'm suprised no one has said anything about their espresso!
Everyone knows already about the pizza. Sure the pizza is tremendous, but the espresso is equally amazing! I reccomend the iced freddo. They usually have a good barista on hand, but I've only had one espresso drink that was only 'okay'.
There are about four other places in Columbia City that serve espresso drinks, but Tutta Bella serves the best by far. It maybe the best coffee in South Seattle. I say 'maybe' because Galaxie on Beacon Hill also serves a fine cup Cafe Victrola and Remo's has pretty darn good drip coffee.
