Ever talk to a juicer? Not the apparatus (or, for that matter, the kind of athlete who's prone to relying on "special enhancements") but rather, a person who juices? Rest assured, if someone in your life juices, you know about it; people are positively evangelical about this stuff. Must be all the vitamins. Anyhow, local juicers have a new mecca -- Juiceateria, a bright little juice bar that opened August 8 in Royal Palm Place in downtown Boca Raton.
