Time has no meaning at Pop’s Nightclub (401 Monsanto Avenue, Sauget, Illinois; 618-274-6720). Lesser bars may concern themselves with things like “closing time” and “last call” — not Pop’s. Open 24 hours every day but Sunday, this Sauget spot is for day-drinkers and night-drinkers and everything-in-betweeners. Your favorite St. Louis bar closes at 3 a.m., but you’re still thirsty? Not a problem; just point your car east. Still got money in your pocket after the nearby strip clubs close? Pop’s will take it off your hands and replace it with something sudsy and cold. On Sundays the staff shoos people out at 10 a.m. and the doors don’t reopen until 11 p.m., but luckily St. Louis has plenty of bars that are open during those hours. Pop’s, meanwhile, will be there for you when those bars aren’t.
