It's not in Clearwater, but right over the Courtney Cambell Causeway in Tampa... Oystercatcher's has the best brunch in the Bay Area hands down. My family and I went there last year for Easter and had a fantastic time. Full oyster and seafood bar, omelette station, carving station, sushi, make your own guacomole and an entire dessert room with a chocolate fountain. (The unlimited mimosas and bloody marys are a nice touch too.) Make reservations beforehand--it's always packed.
