The Sundowner is probably your best bet, although if you are going on a weekend night it can be too crowded to get a large group together easily. Penthouse would be an excellent back up plan. Here is a relavant review of Penthouse I saw elsewhere, it's not my experience so take it with a grain of salt:
"After a trip to the casino with some friends we ended up at Penthouse to make sure we didn't leave with any money. After ordering a reasonably priced bottle of champagne, then another, and looking after the girls well, we were given our own makeshift VIP area. He opened up the basement section which wasn't open since it was mid day, let us choose which girls we wanted and posted a bouncer to make sure no one else came downstairs. Little more champagne and a few hundred dollars later, everyone was naked, the girls were playing with us, toys, each other, you name it. The girls were typical Eastern European, but ey were fun and genuinely seemed to be enjoying themselves. We paid decent money, but felt we got value for it. The owner checked on us, asked if we wanted different/other girls, brought us food etc We were never really pressured to over spend or stay longer three wanted to or taken advantage of. Overall, lots of fun!"
As for take out from any Niagara strip club it is possible with the right girl under the right circumstance. They will often quote you something outrageous at first like $1,000 but will be easily talked down to something more in line with the going rate of $$ to $$$. Timing, personality, charm all matter in this, and some will be insulted by the suggestion. It just depends on who you fancy and what you want to do with them. Make that clear in advance, by the way.
I don't know of any Asian SPs around Niagara right now. Miss Madison at Temptations has a vague asian look but is listed as Canadian, she is pretty well reviewed although I have not seen her.

There is one Asian dancer who works quite a bit at the Downer. Can't remember her name (anyone?) but she is pretty chatty and friendly.
