O. Sansuk Muay Thai Gym Pattaya
O. Sansuk is an active Thai Muay Thai gym on Sukhumvit Soi 61/1. Its official Facebook page was posting on the verification date and matches the live Google Maps address and phone.
No current first-hand price or complete class timetable was published in the sources checked. Message or call the gym before travelling to confirm the session, whether beginners can join, and what gloves or wraps are included. The gym is on the east side of central Pattaya, so use the linked location rather than searching by an English-only name.
