Semi legit massage is common. These places open till 2am too. However there is an after midnight premium tacked on to the cost, bringing your 1hr to $900TWD. You leave happy at this price. Due to high moral standards, you won't find a lot of FS places or offering either. 90% are aunties.
Search "agung tiam" to find your places for potential FS SPs.
Imagine older aunties in 60s with 80's styled makeup, dresses in 90s style to pleasure you . I found them in a pink salon on Snake Alley Market. I turned around once my eyes adjusted to the dimmed lighting.
