The ultra-swank Union Square nightclub Infusion Lounge is turning one this Friday night, and they're celebrating with a lot of drama: Johnny Drama, to be exact. Kevin Dillon, who plays Drama (the fame-loving older brother of Adrian Grenier's superstar Vince) on HBO's Entourage, will be the guest host at the anniversary party, which will also feature DJ Echo, DJ Crooked, and other "surprise celebrity guests" promised by the club. We imagine that they'll have plenty of champagne and smiles for the SF entourages who show up. Want to meet Dillon and celebrate the occasion? Infusion is offering a half-off guestlist if you sign up in advance, allowing partiers in the know to get in the door for $20. (It's $40 for those who show up after 11 or aren't on the list.) Sign up your entourage at their website, and get ready for some fun shenanigans.
