The Mercury Cafe is the ultimate Zone zone -- not just because it offers nutritious dishes that pull from all of the food groups in ways you can easily regroup to fit your ideal zone, but because after you eat, you'll likely be pulled into some swing dancing that will take you straight to your ideal heart-rate target area. For 25 years now, the Merc has been a hip-hoppy, snap-happy spot that serves great food for carnivores and vegetarians (vegans, lacto-ovo, macro-micro, you name it) alike, in a fun atmosphere filled with dancing, music theater, poetry and any kind of art you can think of (and then some). Ponder life's possibilities as you put away an order of Susan Jane's tofu chop with rice and veggies, or a Santa Fe breakfast of beans, rice, corn, cheese and green chile, or shrimp fettuccine tossed with hot peppers and olive oil. Naturally, everything's homemade from whole grains, natural sweeteners and cold-pressed oils; owner Marilyn Megenity even makes her own soda pop. Get with the program at Denver's zone away from home.
