Saturday, June 3 was the beverage company BottleXO’s 2nd birthday. They threw a huge All Caked Up party at their very own XO Bar, featuring free kegs of beer, food, DJs, prize giveaways and fun activities like chugging contests. The whole event started from 4pm until late, and it was a full day of festivities perfect for enjoying XO Bar’s summer street side vibes. Check out more photos of the event on Facebook at Shanghaiist…
