Barbecue is usually a casual affair. Not here. The room reads more upscale bistro than backyard cookout (tufted, maroon leather booths; exposed brick; double-height ceilings). BBQ purists will want to stick to the St. Louis–cut pork ribs and brisket, but Carbon Bar’s lighter fare deserves a hat tip, too. Bourbon-marinated chicken is sweet and succulent and best enjoyed with one of the on-theme cocktail creations like the Pit-Fired Old-Fashioned made with house-smoked bourbon.
