In November 2010, the Ambrosia Café & Catering opened its second location on the ground floor of the U.S. Bank Tower. Not content to serve up standard office-worker lunchtime fare, Ambrosia eschews cold cuts for roasted tri-tip, and Oscar Meyer for Niman Ranch organic all-beef hot dogs in a big, soft bun. There are also great salads and soups. And don’t even get us started on the desserts. They are, quite simply, some of the best in town. The fare may sound simple, but doing simple very, very well isn’t as easy as it looks.
