In my language that is quite an (still!) obscene word. Kids will be reprimanded if they use it the wrong way.
But not so much bars, but these massage houses: the BANK, AQUA, nr. 9 (no, not 69)
Above names: (old post of 5/7/21) Japanese its Kah-wah-ee!. Many bars seem to aim at a certain clientele, or perhaps the owner in the back end hails from there and then chooses a name fit for that. Confusions with other words are usually intended.
Banana in thai is kLuay. Kuay is the name for buffalo (a very common and loved animal by the ever shrinking nr of real farmerboys from Isany) and as its in thai so close to the dirty word for the male organ used as such.
For those wanting to see well equipped Thai: onlyfans, search for kuay-super. Has always 3 cockrings on his dong. Also on some poh-sites like xhamster and boyfriendtv
