Need recs for one night each in scottsdale, phoenix, and tuscon

Traveling through Arizona with my parents and english cousins. Hoping to have lots of tasty mexican and southwestern food while we are there.

So, question is, if you had one night in each of these cities for a mid-priced dinner with 5 adults ( and probably no place with long wait time) where would you go? Tuscon we can bust the budget a bit if that helps. Thanks!
