Can’t cut out of your office the moment the clock strikes 5? This swanky downtown cocktail lounge offers very good $8 mixed drinks, like a particularly potent old-fashioned, until 8 p.m. on weeknights. 111 W. Hubbard St., River North, celestechicago.com

For Outside Drinkers

Saint Lou's Assembly

The one thing about drinking during patio season is there are never enough tables. Not here: A capacious set of steps line the wall of this throwback spot’s outdoor space, all but guaranteeing that you and your friends (and your $2 cans of what the drink menu affectionately calls “lawnmower beers”) will find a place to squeeze in. 664 W. Lake St., West Loop, saintlouschicago.com
