The origin of tapas began when people would go to wine shops in Spain and the bartender would give them small plates of food like chorizo slices to place on top of their wine glasses to keep flies out. Over time, these small plates of food became known as "tapas". The document then lists and describes several famous tapas bars in Seville, Spain, including El Rinconcillo known for spinach and chickpea tapas, Blanco Cerrillo serving fried fish, and Las Columnas de Baco specializing in different codfish dishes. It recommends visiting these and other tapas bars in Seville to sample traditional Spanish small plates and snacks.
