All of the talk about Big Star has centered on its brown liquors, crafty cocktails and ridiculously inexpensive-yet-highly-delicious tacos and other Southwest honkytonk fare. Yet in the city that practically created the hot dog, it's little surprise to see an all-beef Vienna on the menu, albeit one with Arizona roots. The Sonoran dog here gets a proper sheath of bacon, as well as some frijoles charros, plus a healthy squirt of mustard, mayo and green chile hot sauce. Roughly-chopped white onions and red tomatoes reflect its Chicago home. The entire package is sealed in a sturdy, starchy Mexican bolillo roll from Artemio's Bakery down the street on Milwaukee Avenue. Served with a Mexican Coke (that means pure cane sugar, no high fructose corn syrup), it's going to taste even better once that patio opens up in a month or two.
