How do you spell value? At Jack in the Box (NYSE: JBX), you grab a chicken sandwich, throw in two tacos, and slurp a soft drink for a measly $2.69. This "Big Deal" combo meal is one of several new menu items the company launched last quarter as part of an overall reimaging of the company.

When fellow Fool Rick Munarriz picked JBX as a niche winner in December, the stock wasn't on my radar screen. After all, Chipotle Mexican Grill (NYSE: CMG) (NYSE: CMG-B) continues to buck the soft sales trend of eateries, while Buffalo Wild Wings (Nasdaq: BWLD) is flying high.

But first-quarter results at Jack's place are looking solid. Comps at the namesake brand increased 1.5%, marking 18 consecutive quarters of higher comps. Emerging star Qdoba Mexican Grill was no slouch either, notching 4.5% higher comps, making it 34 quarters in a row. Not many restaurant chains are showing this kind of consistent growth.

The bottom line looked tasty as well, with EPS growing 15% to $0.60, blowing away analyst estimates of $0.57. The company has consistently "beat the Street" by more than 10% in each of the past four quarters. Not too shabby.

Food and packaging costs were 170 basis points over prior year on higher dairy and produce costs, but expense savings and gains on the sale of company stores to franchisees more than offset these cost pressures. The company regularly sells established units to franchisees; these gains are part of normal operations, not unusual items.

The reimaging effort continues on pace, with 51 restaurants getting makeovers during the quarter. The new item pipeline is also strong, with five new items introduced during Q1 (including the Big Deal combo), four items rolling out in Q2, and fruit smoothies on tap for a systemwide introduction in Q3.

Niche companies like Jack in the Box occupy a tempting space. They can innovate more quickly than larger quick-service chains such as McDonald's (NYSE: MCD) and Wendy's (NYSE: WEN) can and are less likely to be caught by the law of large numbers.

With Jack in the Box trading at a price-to-earnings multiple of 15, compared with more than 20 for its much larger competitors, this stock just might be a big deal for 2008.
