Leon's Lounge has been a favorite Houston watering hole for decades for very good reason — the bartenders serve up expertly made cocktails that not only taste amazing but also get you thoroughly, happily drunk. We were relieved when Houston's oldest bar reopened after briefly shuttering last year, because it meant the booze- and history-soaked place would be back and serving martinis comprised of mostly vodka (or gin), lilac-colored aviations and the best old fashioneds to be found in the city.
