The ladyboy (katoey) bar scene is its own circuit, and Bangkok has the densest in Thailand. These are go-go style bars — stage, dancers, lady drinks — staffed by trans women, and the city's epicenter is Nana Plaza (Obsession on the ground floor, Cascade and Casanova upstairs). Soi Cowboy has the well-known Cockatoo plus newer venues, and Patpong runs ladyboys in its shows.
Pricing tracks the straight go-go bars closely. Beer runs 140~250฿, lady drinks 200~250฿, and a barfine of 600~1,000฿ at Nana (Soi Cowboy skews higher, 1,000~1,200฿). Take-out is short-time 1,500~2,500฿ or long-time 3,000~4,000฿, settled with her; some Nana bars also rent on-site rooms for 350~500฿. Agree everything before you commit.
The pull is the show and the energy — Nana's ladyboy bars are among the most high-octane rooms in the city. Doors from early evening, peak 21:00~01:00, closing around 02:00. Cowboy and Nana are one BTS stop apart (Nana → Asok), so it's easy to hit both. The 8 bars below are live-ranked by 7-day visitor traffic and recent reviews. Updated daily.
