NEW YORK ( TheStreet) -- Earnings season has been filled with disappointments in the restaurant industry, most recently from the likes of Chipotle Mexican Grill ( CMG) and Starbucks ( SBUX). But there's one steady performer that seems to go unnoticed on Wall Street.I suspect this is all about to change. If you have never heard of Ruth's Hospitality Group ( RUTH), I feel sorry for you because you are probably still searching for that perfect steak. You have also probably missed one of the best stock performances of the year; RUTH is currently up 35% with no meaningful signs of slowing down. The company that operates popular Ruth's Chris Steakhouses across the nation, among other restaurants, is not only the talk of many towns when people recommend a great dining experience. This weekend it also became the talk of my household because the experience likely saved my marriage.
