Quick info on Vanilla Sexy Cafe and Bar, Sukhumvit, Soi 33, next to Peep In, caters to Yiipun, but I am sure your bahts will be good there, too!
It is a mix of a beer bar, a gogo bar and a hostess bar. Got SYT's there. Two big sofa sections for groups or semi-private cubes for one-on-one.

Let's say you found a SYT, you ruba-ruba for an hour and then ST, minimum damage will be around 3,000 bahts. That's comparable to SCB and Nana. The downside is 650 bahts to get in. Some of the girls actually stand outside when business is slow. You might like what you see before going in :O)
