What a COOL hidden gem - It's called The Bassment and features live music, funky decor and interesting cocktails. The entrance is kind of hidden (directly below Hampton Social in River North) and if you go before 9, there's no cover charge. The place features art of famous artists, as well as a drink menu named after them ("The Marley, The Madonna, The Winehouse," etc.) They even have a $20 cocktail served in a miniature bathtub. The atmosphere was amazing and I definitely recommend this place!
