Beer bars:
ST 1.5-2k. LT 3-4k. Bars with rooms above you're looking 1.5k and 500 for the room on Soi 6.
Bar fines all over the shop, but they are high, too high. 600+ usually. Girl drinks in beer bars 150-200. Maybe some are cheaper in places like Tree Town.
Gogos - another posted Reported 2k BF and 5k ST in Pinup, which is an expensive place. Don't expect a gogo girl for less than 10k all night with BF + drinks. LD's in a gogo 220-250. Most BF's seem to be 1.5k+ now, with most being 2k. A windmill girl recently quoted me 3k but I'm sure she said the BF was 3k but I may have misheard.
Gentleman's clubs are where the value is at. Often 1k for the girl, 300 for the room. Cheap drinks. Most seem to be expat focussed. Hit and miss if you find any lookers, a lot of older girls. I'm not really into them, don't really want to see a fat bird sucking some old bloke off in the corner personally but each to their own.
Thai Friendly 1.2k-2k. Seems some of the stunners who have insta followers will ask for 5k.
Girls in the Walking Street clubs at 3am, 1.5-2K ST but many will stay the night for not much more.
It's not cheap but there is value to be had. Best way is to put a good pair of shoes on and get walking the bars and massage shops. You will always find something that takes your fancy.
