Someone asked about bars in Hua Hin and although I am not the best person to speak on the subject I'll start the thread and let others comment if they want to.
I think the first thing to say that is that if you are looking for a Pattaya like experience then go to Pattaya. Hua Hin has a central area with about forty or so beer bars, a few others scattered around the perimeter and that is pretty much it.
There are no go-go bars, in fact there are no bars that you could not take your children to.
There are two (I think) gay bars and a single lady boy cabaret.
All of the bars employ a few girls and most have one or two ladyboys as well. The standard of looks is not particularly high ( I saw a couple of ladies who must have been in their late 50's ) nor do the girls seem particularly interested in going with customers; I have been in bars on several occasions with my wife where the girls have nearly had to be frog marched by the mamasan to sit with a customer.
On the other hand my son was always made welcome and got a lot of fuss from the girls and they are happy to play pool with him so that I can have a quiet beer.
Bar fine is 200 and the girls expect 1000 for short time no doubt negotiable depending on time of month etc.
There is one - count 'em, one - body massage establishment. In the interests of research I stuck my face in to enquire. 1400 - 1800 depending on time required and again there were no girls, on the day I called, that I would be remotely interested in.
There are a couple of discos - you will have to club together and raise a bribe if you want me to investigate, as there is a strict limit on what I am prepared to do for free, and going to discos is not on the list.
If you enjoy pool however you could be well served, there seems to be a fairly active pool league here and another bar that seems to be devoted to the local golfers.
I think I once saw a girl working the street, but the police are likely to discourage anything so obvious.
There are also a few Thai karaoke places - same rule as with the discos applies I'm afraid.
And that is that. I am sure that there must be other opportunities but my advice would be that it is easier and cheaper to go to Pattaya.
