When you tire of lomo saltado, pan con bistec, and ropa vieja; when your digestive system longs for a little roughage and your taste buds for a cleanse; and when your Levi's are getting tight around the midsection, sniff out the greener pastures of Govinda's Garden. Hidden behind downtown's fading flagship Macy's, it's too easy to miss. Its forest-colored décor and smattering of chairs and tables are a serene respite from the rest of South Miami Avenue. Order the rainbow-hued quinoa salad ($9.50). You'll be presented with an artfully overflowing bowl of bright-green spinach leaves, crimson peppers, mint-colored cucumbers, burnished brown raisins, purple cabbage, and taupe cashews topped with a sunny yellow lemon slice. For $2.50, add perfectly browned tofu as a topper. Dressing is optional. Quiet, friendly waitresses will shoot coy smiles your way as you chomp happily on your rabbit food. Your innards (and outards) will thank you.
