Octagon is one of the many spa salons in the area. The location is pretty good; right off of Delaney Rd and 41 (good if you live in the northern suburbs). The staff is friendly (for the most part, I have had a couple of snotty hairdressers), the haircuts are good (again, for the most part) and the prices are reasonable compared to other spas. I wouldn't say the place is outstanding; there are definitly better spas in the Chicago area. But if you want a reasonably prices one, this place is worth it. Haircuts run 30 - 40 dollars and highlights are around 80-90 dollars. There is also a nail salon, other spa treatments (massages, etc).
