Almost hidden in the downtown maul of electronics and shoe stores is a sportinggoods retailer that caters to South American visitors -- like everyone else downtown -- but also remains attractive to locals with an athletically active bent. A family-owned business, Miami Fantasias sells everything the weekend warrior might need, from fishing poles to Ping-Pong paddles, tennis rackets to heart monitors, and even that spear gun you might have been eyeing (nervously). Miami Fantasias excels most notably as a dive shop. New certification classes start every Monday. Dive trips on one of the store's three boats depart from Miami every day. Longevity in cutthroat downtown is one indication of the store's ability to satisfy its customers. Founded in 1978, Fantasias has grown into a thriving business, today employing more than 45 helpful, consumer-oriented employees. Jog in. Dive in. Ping-Pong paddle in. Just get in.
