Frank's is a great place in Tucson for breakfast! It is filled with couples on dates, regulars who probably eat every meal there, and the occasional tourist who has read it about it. By day it is Frank's, a typical diner, serving a truly amazing breakfast. By night it transforms to "Francisco's," a Mexican eatery. It is very casual, pretty noisy, and fun!
I'm a transplanted New Yorker who loves the Tucson climate. On New Year's Day I have a bit of fun calling my (snowbound) east coast friends to announce that I'm drinking coffee while sitting on my patio. (:
