Having been a pooner for roughly thirteen years, and having a penchant for the Asian persuasion, I have a pretty good grasp of most of the shops around the area.
Xiao-dimsum has been mostly reliable for me. Their girls are listed with a mix of real and fake pics, but the fake pics usually are a close approximation of what you'll get but beware of breast measurements listed on the site, and that of K604. They're always bigger than what you'll get. But there is a legitimate reason for that which I learned when I had a date with one of Xiao's girls. On the site, she was listed as an E cup. Because we had a good rapport early on, I brought this up because her boobs, while big, were about a D cup. She showed me her bra and indeed it was an "E" cup. It is due to how measurements are taken in Asian countries compared to North America where they are on the smaller side while using the same letters. A D cup in an Asian country may be a C cup here, or even a B cup, and so forth. With this in mind, their listed stats appear to have been on point with each girl I've met from there. The age factor is more of a gamble, but as AF said one time a few years ago when I publicly challenged the age listing for one of his girls as being half of her real age, "Everyone does it" sums up what you'll get from every shop, with some doing it more than others. Xiao has a mix of Korean and Chinese girls, mostly Korean, and are now bringing in more Japanese girls as well and their ages are usually at least within the same decade as the girl's real age.
Korean604.com has been pretty good for me but not quite as consistent as Xiao. Full disclosure, I haven't used them as often as I used to only because of convenience but some of their ladies of late have been quite good and of course there is always the reliable K and one of my all time faves, Stella when she is in town. Definitely fake pics or pics taken several years ago is usually what you'll see but the stats listed tend to be fairly accurate, but age is usually not very close.
Asian Fever? I've tried them three times, once when they were a different name that escapes me at the moment. All three experiences were just ok or borderline bad but because I publicly shared some negative opinions here on PERB I was blacklisted, which is fine, because few of their ladies have seemed worth visiting since sometimes "real photos" is a little too real, if you get my drift. And contrary to what AF says ad nauseam, they are not the only shop that has "real pics". They are however the only shop that pays for a photo and video shoot to create content exclusively for their website. It's smart as they own the content and the girls can't take it with them when they leave. AF will now try to rebut my comments but this is my opinion based on my experience dealing with this shop. Others have a high opinion of them so they're obviously a good fit for another type of customer.
Hope that helps.
