Chuy’s Holdings Inc., the casual-dining Mexican restaurant operator, debuted on the public market Tuesday, closing up 15.9%. The 36-unit Austin, Texas-based company offered 5.8 million shares at $13 each, the top end of its forecasted price offering between $11 and $13 per share. Chuy's initial performance bodes well for Southlake, Texas-based Del Frisco’s Restaurant Group, which is scheduled to debut on the market Friday. In comparison to Chuy’s first-day spike Tuesday, the Dow fell 0.8% and Nasdaq fell 0.9%. Wall Street darlings like Chipotle and McDonald’s were also hit hard by investors as the companies reported depressed sales and earnings news.
