When our dining companion slipped into the bathroom at this swanky Scottsdale eatery and stayed a while, we assumed she was sniffing some Bolivian "marching powder" — or getting it on with a hot waiter. But when she returned, she wasn't runny-nosed or chatty; she was rapturous. "Dude, you have got to try the toilet," she breathed. And for once, she was right: These W.C.s really are to die for, from the heated toilet seats to a seat that lifts and rotates its plastic sheath on cue for each new customer, to the incredibly nifty bidets. We guarantee you'll return to your table not only feeling cleaner but positively excited. It's got to be the most fun you can have in a public restroom without breaking the law.
