The best time to visit Carnaval is weekdays from noon to 3:00 p.m. Why? Every Monday through Friday this market offers a hot lunch buffet that features different homemade dishes, from traditional specialties like feijoada to adopted Brazilian favorites such as beef stroganoff. Choose from anything on the buffet for only $7.50 per pound; then grab one of the coveted indoor seats and tuck in. Even if you can't make it during lunchtime, this place serves great snacks -- warm p?o de quiejo as well as empanadas and panini sandwiches -- all day. And if your sweet tooth is aching for some treats, get there early and grab some brigadeiros before they run out. Of course, Carnaval's shelves are well stocked with a wide selection of Brazilian products -- including guaran? and requeij?o -- if you prefer cooking at home.
