After the unexpected success of the Zaitunay Bay edition, it was only natural to do the Gemmayzeh edition one. Below is a Google Map detailing the locations of parkings I frequent the most. Personally, I’d recommend you find a spot on Mar Mikhael street, but because of the bourgeoning nightlife district there recently, it’s getting tougher to find a parking spot.
My favorite spot is the Freres school’s parking, because the proceeds go to fund scholarships in the school (or at least that’s what the parking ticket says). It’s at the beginning of Gemmayzeh too, so will allow you to do the entire pub-route. There are two others on Pasteur street, parallel to Gouraud street (the main Gemmayzeh street). One is in front of the European Union’s HQ in Lebanon (5,000 LBP) and the other is near Coop D’Etat and Bulldog (5,000 LBP).
There are several smaller ones also, which are garages in the day, and parking by night. They’re tight though, and you might get your car busted there just as much as when you use a valet.
