Not news: Al fresco dining in the Valley October through May is sublime; al fresco dining in the Valley June through September is hell. Until now, thanks to this Camelback Corridor restaurant (formerly Houston's in the Esplanade complex until it moved down the street and changed its name in 2011). Grab a cushy seat on the spacious patio (no misters, thank goodness), a cold libation, and let the cooling begin with air-conditioners built into the tables. Give it a couple of minutes, but you'll be chilling soon enough. The system uses no CFC refrigerants, adds no moisture to air, and uses 90 percent less energy than standard air conditioners. So how does it work? Beats us, but it certainly makes patio dining a viable option during a season when most of us can't stand to be outdoors for any more time than is absolutely necessary.
