Fantastic location, but service somehow made me wanting for more. I got a gel mani with one of their pre-set designs ($48). While the product was decent enough, as other reviews state, they only really apply the polish as opposed to a full manicure. I had to get my pre-existing gel mani removed, which cost $15 alone. I needed my nails shorter, but because they don't have nail clippers, the technician had to file them down instead.
I love Japanese nail art and I'm stoked that TNAB provides this service on the Strip, but I'll stick to 3 stars for now unless they can provide full mani service.
