STAFF PICK: Austin's has ruled Tucson since 1958, with no end to its reign in sight. You can still sit at the counter and watch the teenage soda jerks make irresistible concoctions. The milkshakes are sublime, served in a glass with the tall frosty stainless-steel mixing cup on the side so you can pour your own refill. You can choose from the traditional flavors or invent your own 21st-century combinations like mango-ginger and chocolate cherry pumpkin supreme. The absolute definition of guilty pleasure.
