The Age of Aquarius is alive and well at the Main Street Café. Tofu, soy burgers, a salad bar, and hummus are all on the lengthy menu that accentuates the vegetarian. Fruit and vegetable juices are on tap to wash down this healthy fare. Sun lovers can sit at tables outside. But if inside is your thing, man, the walls are decorated with the work of local artists. Christmas lights also help bring the joint, uh, place, a comfortable, artsy feel. A small makeshift stage is used for music (including blues, open-mike, and folk) Thursday through Saturday. And if you're not on a health kick, the place offers roast beef, a decent beer selection, and coffee galore. The adjoining store cements the Main Street Café's flower-power ethic. Here you can find crystals, pottery, used compact discs, records, dashiki clothing, incense, and guitar strings. For those who want positive vibes with a modern twist, there are three Internet-ready computers, which rent for five dollars per hour.
