Sweet Mango Cafe Renting Its Roof Deck? Prince Of Petworth May 13, 2008 at 10:41pm IMG_8549, originally uploaded by Prince of Petworth. I’m not sure if the roof deck was rented or not but there was some sort of party going on this past weekend. I think it was a birthday party. Pretty sweet spot. Note to self – have a future PoP happy hour on the Sweet Mango roof deck. Right?
