There is never enough team spirit at Duffy's Sports Grill in Deerfield Beach. Football helmets line the aisles, and the giant bar area boasts 13 huge projector screens that play every game and sport imaginable. If that's not sports overload, young women in jerseys offer enthusiastic "how are yas?" at every corner while they walk past restaurant-area walls littered with photos of athletic icons such as Jack Nicklaus, Lance Armstrong, and Mickey Mantle. Regulars readily offer up that it's the best happy hour in town, with two-for-one on everything from 4 p.m. to close everyday.
