If you've ever been to Spa Castle in Queens, you know what heaven is. (If you go on a weekday, that is.)

There are a few things about the spa that are frustating, however. There can be lots of families and children - especially on the weekends - and it's hard to get to without a car. (For those on public transit: take the 7 to the last stop, Flushing-Main St., and catch the Spa Castle shuttle.)

But Spa Castle is a smart company, and they are opening up a Manhattan location in November. Called Spa Castle Premier, it will be a place for "zen" seekers of a certain age. You must be 16 to enter.
