I was in HK this past wkd .. haven't been in almost 8 years and went to the saunas there for the 1st time. Both are in the TST area:
Galaxy: $56 HK ... a not so clean, old sauna with a VERY wide mix of guys .. I paid when I got there which is not the usual practice I guess as the front desk guy (later shift) started screaming at me for not paying when I left.
ABC: $130. Pricey but clean and small place. Less than 10 guys when I came but managed to hook up with 2 cute muscle btms
