An unlikely combination in an unlikely place. During the day this little storefront, wedged between an antique shop and a plumbing-supply store near the Miami-Coral Gables frontier, is mostly a haircut hangout. Nelson, an affable, experienced barber, dispenses 'dos and relationship advice, in both English and Spanish, to customers who recline in two barbers' chairs. DJ Flex Perez devotes one wall to baggy jeans and T-shirts the size of pup tents. Perez also oversees a rack of vinyl for party-spinning (heavy on rap and house), a few CDs, some caps, and some videos for sale. But the place's real genius lies in the crossmarketing. On his business cards, Perez emphasizes Nelson's scissors skillz, including "Fadez," "Caesars," and "Close Cuts." If you're kickin' it old-school, Nelson offers a half-price senior-citizen discount on weekdays -- five bucks.
