Posh is a hookah lounge located in the Waverly Condominium complex about 1/4 mile north of Las Olas Blvd. I don't usually patronize places that promote any kind of smoking, so you'll have to try it yourself.
Take the online reviews with a grain of salt as there are a lot of "friends" in the condo pumping it up. I'm pretty sure that the place is up for sale (for a price they have no chance of getting).
I can walk to this place and have never been here and likely never will.
