Bro Ip, the "Tawandeang" that u have been to at Klong Tan is called "Tawandeang Chiwit" and directly opposite is another called "Tawandeang Issan" but none of these 2 r related to the Tawandeang at Rama 3 or Ramitra.
I think they are just riding on the "tawandeang" name. I've been to both Rama 3 and Chiwit. I think both places are not a pick up joint per say but sure u can "chon keaw" and join the next table after dinner when everyone is more tipsy and relaxed so make sure tip "dek serve" well, IMHO Bht100 is more than enough, so they can get a table next to some hot "saos" for you
Bro Horny Angel, your bottle can keep and u will not b charged covers. This is SOP at all clubs in Bangkok. IMHO Scratch Dog is better compared to Climax and you can also sign in another 4 or 5 guests too. Don't forget write FR and choke dee naa krap
