Yep, seen enough of this profiling myself. What's happened locally is that the Palace and Skybar were known as being "brown" & Asian bars respectively. When they both shut down I think the other bars in town didn't necessarily want that crowd migrating to their places, hence the "oh, it's a private party BS" to bar the gates.
Had this happen to friends of myself. One of them purposely tested this as they sent the white friends of their group in ahead and they got in no problem. (This was at the Mynt - With their 3 foot wide main staircase to cover 3 floors I always expect to read about some German style disco fire that incinerates 200 about this place). The brown guys in their group got turned away of course.
There is a train of thought amongst bar owners rooted in economics that partially drives this discriminatory policy. Fact is many Asians can't drink a lot of alcohol as the lack of a enzyme to process the alcohol makes them cheap drunks, and not much is bought - reducing bar profits. Both groups tend to use a bar or club as a place to hang out rather than get blasted and spend gobs of money - which of course bar owners dislike. Add to that the alleged gang connections and what not and suddenly bar owners would rather not have this group in there....
I think Victor Choy owns a few establishments (The Whiskey I think...) and I believe he uses similar policies...
That's why I try not to support any of these places with my moolah.... that and I'm not 19 yrs old anymore... by a longshot...
