After Buffalo Wild Wings (BWLD) reported revenue and earnings for the first quarter of its 2014 fiscal year, shares rose 5% on April 29, 2014 to close at $140.14. Now, with shares of the chicken wing establishment trading 61% above their 52-week low of $86.96, should investors consider leaving the roost and jumping into Texas Roadhouse (TXRH -0.07%)? Or can the restaurant's success continue flying higher?

Buffalo Wild Wings's high flying quarter
For the quarter, Buffalo Wild Wings reported revenue of $367.9 million. In addition to beating the $363 million analysts anticipated, the company's top-line performance was a jaw-dropping 21% higher than the $304.4 million management reported in the same quarter last year. According to the company's earnings release, the increase in revenue was driven by a combination of a higher store count and rising comparable-store sales.

Over the past year, Buffalo Wild Wings added 101 restaurant locations, bringing its store count from 911 to 1,012. Fifty five of these restaurant additions were franchised operations, while the remaining 46 additions were company-owned. Despite this disparity in growth, the company-owned locations enjoyed a stronger growth rate, with comparable-store sales increasing 6.6% compared to the 5% sported by its franchisees.

From a profitability perspective, Buffalo Wild Wings did even better. For the quarter, the company reported earnings per share of $1.49. This handsomely surpassed the $1.35 Mr. Market wanted to see and was 71% higher than the $0.87 the company reported during the first quarter of 2013.

On top of enjoying a higher level of sales, the company saw its cost structure fall in relation to revenue. One of the primary drivers behind this improvement was the company's cost of sales, which fell from 30.6% of revenue to 26.5% as chicken prices dropped and the company's method for pricing chicken was modified.
