I've visited Tibet Foot Massage a couple of times now, and figured it was a good time to finally review it.
Both times I had Rex, and he was always polite, accomodating, and best of all, a GREAT masseuse. As with some of the other massage spots on Spring Mtn, there is always quite a bit of background noise to accompany the instrumental music playing in the background (i.e the masseuse taking a cell phone call or getting up in the middle of my massage to talk to a guest who's just walked in). I've learned to deal with that after many massages on Spring Mtn. I just tuned it out and focused on being calm and relaxed.
It's not your 4-star establishment but for the price and the quality of massage you receive, it's definitely worth it. I'm moving out of Vegas and I'll surely miss it!
