Cesar Castillo, manager at the Lone Tree location, says the restaurants are no longer affiliated with Fatburger (they've been removed from the corporate website's directory, too) and that Epic Grill is a new concept -- albeit one similar to that of Fatburger, since it features some of the same menu items.
"We're the same guys, we just changed the name," he says. "We're doing the same stuff but with more: salads, sandwiches and all that stuff."
The idea, he says, is to start with the four current locations of Epic Grill -- in Lone Tree, Highland Ranch and two in Aurora -- and grow from there into a new, bigger, Denver-based chain.
