I lived in Jordan a few years back. There was a Hookah lounge i used to go to which i am trying to remember where it was.
I know there are many in Amman but i will describe the place.
Not sure which dawar it is close to but the place is about 10/15 mins drive from Gardens. Once you get off the main road there is a place to park cars, along that road there is a club/disco and a few shops. if you go further in you have to park your car and walk as no cars can go through that street. The place is a 2 minute walk from the street parking. there are a few Shisha Cafes surrounded by green bushes and fairy lights.
One cafe is a small one in the middle of the street and the one other is on the left handside decently big 2 floor restuarant/shisha cafe. I think there might have been another cafe also but not sure.
The Shisha Cafe was also a restaurant and the outside seating area is decently sized. there is also a second floor. That place is always busy with people at night.
Im sorry if this description is very vague but from living in jordan i know how easy it is to describe a place and people know. haha looking forward for your replies if you give me names i will try to find out which ones the right one.
