For hanging out on a lonely Saturday evening, I used to go to New World hotel in Makati, beside Greenbelt. They have this nice bar in the lobby area, the Bar Rogue, perfect for a single dude like me. They have a nice selection of drinks, nice music to enjoy with your drink. They have pretty servers as well. I got close to one of them way back in 2013, hung out a few times after her shift.. Although I Never got the chance to get in bed with her, her company was enough for me to keep going back. The bar is rarely full, so you could always chat up with the ladies who serve there, they are friendly as well. Just don't act creepy and they will reciprocate it with a nice conversation. Who knows, you might get lucky enough to ask them out like I did. Cheers.
