I got back into guitar about 2 years ago and I've developed a habit of visiting any store in town that sells guitars. While they do have a great selection I'd say there are better shops in town for just guitars (they don't really carry any Gibson product, but have Martin and Taylor)
That being said this is a very cool, historic, music shop in Mesa. It's been around for a very long time from what I can tell and this seems like a GO-TO spot for musical students of any type. They provide space for lessons, sheet music, knowledge, etc. Fun spot but just not guitar centric.
