For bespoke cocktails mixed in a lively atmosphere, head to the Collins Bar in downtown Birmingham. Just tell the bartenders what you like, and they’ll whip up a custom-crafted drink for just $8 to $10. Take your cocktail to the street-side patio, or pair it with such upmarket bar bites as pigs in a blanket made with bourbon-glazed pork belly and pot roast “pot” pie. Before you get tipsy, be sure to examine the enormous periodic table of elements behind the bar: It pays homage to notable people and places in Birmingham. And for those who want to get in on the Collins cocktail action, sign up for a one- or two-hour small-group class.
