I've operated in Beirut with 2 different companies having many layovers there with my first employer.
Once I even brought my wife with me.
Downtown is beautiful. We went out to a caves in the mountain called Jeita Grotto.

Been there many times. Out by night in a club, having dinner... and no, no single guy considered Beirut as a dangerous place.
Plenty of expats, american university...
