I can confirm as I live close to the area. Liang’s (formerly the Sun Spa) is in Wynnefield Heights, next to New China restaurant (their wings are great), also Chris’s Pizza.
Can also confirm I saw the provider years ago when it was Sun Spa, advertising the typical beauties, provider was 50’s maybe 60’s, grandmom bod. I declined the extra help that day as I particularly needed just a massage.
