Beer, Buffalo wings, sports on TV, students watching sports on TV. In most American cities, the college sports bar is a common occurrence. Not here in Miami. In fact the chief representative of this genre is a little bar near the University of Miami. The exterior of Duffy's signals safe haven -- a green shamrock, a sign that reads "Sports Grill," and a UM flag. Inside it's even better. Comfy booths, overflowing pitchers of beer, and, most important, fifteen TV sets tuned to -- yes -- sports. The place, which has been serving Miami since 1955, has the two essentials -- pitchers of Rolling Rock for $5.50, and platters of Buffalo wings for less than seven bucks. Most Thursday nights feature a rib special ($11.50 for a full slab). But beware, Gators and Seminoles: This is not any ordinary sports bar; this is a Canes sports bar.
