I've been to Pipes Plus a handful of times now. Every time I get the same experience consisting of excellent service, good prices, and a nice atmosphere. It's not exactly the prettiest Hookah bar I've been to(Kasbah is prettier), but it feels much more "Austin" to me. In exchange the prices are much better and you aren't nickel and dimed at all. A flat fee for as many flavors of shisha you want and as many coals as you may need.
I can't say I've ever finished off a Hookah at Pipes Plus...my longest session was a good two hours! Not to mention the service is the best I've ever had. I was checked on at least one to two times an hour and my coals were replaced as needed. I've been to two other Hookah Bars in Austin and never I have received this type of service.
To make things better, there are always friendly people hanging out that creates a nice atmosphere. Chill music playing in the background sets the mood just right. Pipes Plus is great, I just wish they were open later
Pros: Service, Prices, Atmosphere, Hookah
Cons: Only open till Midnight
