ok now for a SERIOUS answer ... from someone who has actually clubbed in lebanon!
yes its safe in lebanon so long as u avoid hizbulla areas ... but if ur into the nightlife, u won't be wandering into those areas anyways!
Red Carpet in Gemmayze is my all time favorite .. nothing too special about it, but great staff, great vibe, great mixture of music (most nights) and always packed!
a lot of people love B018 (I'm not one of them): it's an INCREDIBLE design (under ground and the roof opens up), it doesn't open its doors until 3 AM (yea!) and by then everyone is either drunk or exhausted from other clubs .. and they play rave music... basically its the after clubbing sloppy make out spot!
sky bar is another cool one ... its on a roof over looking beirut http://www.youtube.com/watch?v=-cW0VLu3mmo&feature=related
btw all these places, if u plan on going during the weekend u better reserve before hand.
there are loads of party 'places' .. gemmayze I guess would be the latest although the residents have kinda been ticked lately because of the noise, traffic and vomit and so the government has enforced a curfew on some of the places ... red carpet is not one of them THANK GOD!
and yes it is THE party place in the middle east ... the reputation is well deserved!
Let me know if u want some more .. good luck, enjoy the trip, the nightlife u won't be forgetting anytime soon ... and take pictures!
