Looks like business at Del Frisco's Double Eagle Steak House, the 23,000-square-foot restaurant that opened to much fanfare in December 2012, is not as robust as management had hoped. During an earnings call with analysts this week, Del Frisco's Restaurant Group LLC, which owns the Chicago restaurant, said earnings would be lower than forecast for the company. Management attributed the downgrade to problems in Chicago and in Miami. "This was one that hit us square in the eyes," Del Frisco's CEO Mark Mednansky told analysts.

However, management said sales did not rebound after the thaw. "With good weather, we were severely disappointed that our sales didn't come back to where they were last year," he said.
