Shares of Texas Roadhouse (NASDAQ: TXRH) were lassoed last week, shedding 12.48% of their value after the casual steakhouse chain posted disappointing quarterly results. Restaurant margin contracted at Texas Roadhouse, as wage-rate inflation teamed up with higher costs related to payroll taxes, insurance reserve adjustments, and gift-card fees to gnaw away at profitability. Nearly half of the nine new restaurants Texas Roadhouse opened during the fourth quarter were Bubba's 33, a multi-platform concept that serves up burgers, pizza, and beer in either a casual-dining, sports-bar or outdoor setting.
