Melting Pot Restaurants Inc., a chain of 144 fondue restaurants, is changing its name to reflect the privately held Tampa company's broader portfolio of dining concepts. The new name is Front Burner Brands. It will include the company's six GrillSmith restaurants, a still-to-be-launched fast-casual artisan pizza/soups/pasta restaurant called Peel and Burger 21, a concept conceived by Clearwater chef Chris Ponte. The company signed a lease at 9664 W Linebaugh Ave. in Westchase in Northwest Hillsborough County for the first Burger 21 which opens in October. The menu features 21 types of burgers, new variations of hot dogs and a milk shake bar. The fondue restaurants will keep the Melting Pot name. It's only the parent company that gets the new moniker.
