River Road. 299-7799. foxrc.com/restaurants/zinburger-wine-burger-bar Tucson's first Zinburger, part of Fox Restaurant Concepts, replaced the upscale Bistro Zin on East River Road in 2007. Arizona restaurateur Sam Fox, who got his start in Tucson, then doubled down by opening a second location in the old home of his Montana Avenue in 2011. Zinburger offers a strong selection of specialty burgers, including the $10 El Diablo, which comes with pepper jack cheese, jalape–os, caramelized onions and a chipotle mayo. The most expensive option on the burger menu is the Kobe Burger ($15), which is served with Cheddar cheese, wild mushrooms and mayonnaise. Hydrologist Andy MacLeod enjoys eating the Diablo burger with a turkey patty at the Grant Road spot. "It is so full of flavor," he said. "I like the chiles and mayo that they use." Marcia Ring, the director of marketing and communications at Tohono Chul Park, prefers the Plain & Simple Burger ($9), with lettuce, tomato and mayo. "They use these thick patties of high-quality Angus that melt in your mouth," she said.
