Built to resemble Rome's Colosseum yet surprisingly sophisticated inside, this 1,000-seat restaurant—the largest Hard Rock Cafe in the world–is huge, yet getting a seat at lunch or dinner can still require a long wait. The music is always loud and the walls are filled with rock memorabilia. Burgers are made from ground beef and brisket. Barbecued meats are smoked on-site. And entrées include a cowboy rib eye and grilled Norwegian salmon.
