The High Lonesome is no dive bar like its predecessor, the Arabian Bar. The bottle shelves are too precise and tidy, the clientele too young and attractive. But the place is still dark, comfortable and inviting, with few windows to let in annoying things like sunlight or a summer breeze. Denver has its share of patio drinkers in their tank tops and flip-flops, but you won’t find them here. The High Lonesome is built for folks without a care for the outside world while they’re hunkered down over rare bourbons or local beers.
