Late Bar
Late Bar (Chicago) is indeed open late (4 a.m. on Fridays and 5 a.m. on Saturdays). Home to the original Planet Earth party (RIP DJ Dave Roberts). Saturdays continue to be the most popular night! On the drink front, Late Bar is on the forefront, offering sugar-free, vegan-friendly and gluten-free options!
