For the price of a designer sandwich on South Beach you can get an entire meal (dessert included) at Here Comes the Sun, one of South Florida's original health food stores. Between the hours of 4:00 and 6:30 p.m., hundreds of bargain-conscious diners come for the $7.95 special, which buys a choice of about a dozen entrées, soup or salad, coffee or tea, and a small frozen yogurt (three flavors are offered daily so that regulars don't get bored). We especially like the blackened grouper, the vegetarian lasagna and the eggplant casserole, or, for a dollar more, a meaty and moist salmon fillet. Don't be turned off by the health food designation; it's real food cooked to order with plenty of cheesy, starchy extras on the side if you want.
