I'll be in Tucson for business later this month/early May.
The only thread I've found on Tucson is
this one from 2004 which mostly discusses Pizzeria Bianco, in Phoenix.
For these types of trips, I usually like a business-casual restaurant with a nice bar, where it won't seem out of place if I'm flipping through a file, semi-working, while I eat at the bar. But, of course, it should also have good food. (I'm not looking for a taco stand on this trip.)
I don't want to eat at my hotel. Does anyone have any recommendations?
