A high-protein diet can help build muscle, which comes in handy for fighting off a shark that is also on a high-protein diet. Take a bite out of the circle of life with today's Groupon: for $5, you get $10 worth of burgers and drinks at Fresh & Fast Burgers.

At Fresh & Fast Burgers, guests chow down on fresh, never-frozen, high-quality beef patties served up quickly.
