Visited Big Boy bar on the 21st and thought would offer my observations. Am now killing time before my flight out so turned out longer than I intended, readers interested in dry facts please only refer to the next paragraph, khop khun krap.
Tl;dr drinks at 400 baht, only Asian customers during my visit, while some boys were offered drinks didn't see any offs, shows similar to other bars performed at 10:30, around 12, and 1.
The bar itself is indeed difficult to find and I would not have known of it without the help of this forum. Even with basic instructions (near derby king) I had to walk past it a couple of times before finding the entrance. Its entrance is next to a massage shop and while some Asian customers were deciding whether to get a massage (from the sheepish expression on one patron, maybe more than just massages?), I walked up to the barker for the bar and indicated I wanted in (I'd already walked past a couple times and he hadn't tried to get my attention - do I not look like I would enjoy watching naked boys on stage?) There was no price indicated on the menu, so I asked him the price (tao rai krap) to which he replied 400 baht (my efforts in learning my neung song sam sis wasted once again).
Up the flight of stairs to discover the establishment to be around at half occupancy. They seemed to be mostly local (of both genders) with some Chinese? mixed in, if I had to guess. Indeed, during my stay, I think I only saw Asian customers. Ordered water (nam kaew, but I think I messed up the accent because the mamasan seemed amused), upon which I discovered this bar only had bottled water.
I arrived close to 11, and the show soon ended with the mamasan promising the next one would begin in 40 minutes. Most of the customers left at this time, and only a couple of Japanese (of the fairer sex) arrived later so the bar was left sadly empty but I was offered a seat close to the stage, so silver linings? During the interval the boys came up on stage (2 groups that rotated every so often), more than 10 and similar to the number of boys at Hotmale, to my estimation. Some of them, like the bar name suggested, were big but had seen some years, but there were younger ones too. I had already offed a boy from another bar and was waiting for him to arrive so didn't call anyone over, but there were a couple I wouldn't have minded getting to know better.
Soon after my boy arrived to discover that he and the mamasan knew each other (he used to be a manager at the building he stayed in?). As for the show, I thought it was similar to the shows at the other bars with a mixture of boys and lip syncing, but my boy was less than impressed by the show (mai sanuk) and he would be the expert on such matters. The show didn't feel too long, with the next one promised at 1am. We left (drinks were indeed si roi baht), grabbed some food at foodland and retired to the hotel. When we were leaving, one of the boys grabbed me and told me that he had seen me the other day going into another bar?, which told me that it was indeed time to head back home.
