Most of the time the 20-year-old Uptown tavern Big Chicks smells like a bar. But every Sunday, in a gesture of appreciation to her regulars, Michelle Fire closes her neighboring restaurant, Tweet Let's Eat, and replaces the eau de Leinenkugel with the sweet scent of fried chicken and biscuits, lasagna, or tacos. In addition to meat and veggie entrees the free buffet always includes organic salad, dessert, and fresh fruit. In the summertime Fire moves the meal onto the patio to cook up barbecue with all the fixings. The eating starts at 4 PM; you can call ahead or check the Web site to find out what's on the menu.
