Darden Restaurants (DRI 0.46%) -- owner of casual restaurant chains including Olive Garden, LongHorn Steakhouse, and Cheddar's Scratch Kitchen -- turned in better-than-expected results for its final earnings report of the calendar year. The multi-chain operator has been benefiting from a rebound in the restaurant industry this year, slowly scaling back discounts to boost profitability. Though it's been a winning strategy recently, Darden is hardly firing on all cylinders.

Casual-dining value on the upswing

Through the first two quarters of Darden's 2019 fiscal year (the six-month period ending Nov. 25, 2018), total sales are up 5.7% year over year. This sales growth was driven primarily by 4.4% and 3% same-store sales gains at Olive Garden and LongHorn Steakhouse, respectively.

Not all is going well, though. Cheddar's Scratch Kitchen, which Darden purchased in early 2017 for $780 million, has been struggling under the tutelage of its new owner. Same-store sales for that chain declined 2% in fiscal 2018, and the metric is down another 4% through the first six months of the current fiscal year. There are only 158 Cheddar's locations, but that's still a sizable chunk of Darden's total 1,762 store count.

It's also worth noting that Olive Garden and LongHorn's same-store sales increases are mostly due to a more favorable menu mix and price increases. Foot traffic is up only 0.4% at Olive Garden so far this year and down 0.2% at LongHorn. That, paired with the lackluster numbers from Cheddar's, is indicative of a hyper-competitive restaurant industry. According to research group TDn2K, same-store sales at the average dining-out establishment have increased slightly in 2018, but foot traffic continues to decline. For example, in the three-month period ending November 2018, comparable sales were up 1% but foot traffic was down almost 2%.

Falling same-store traffic has been a stubborn metric for restaurant chains for years, as the industry has rapidly added locations to accommodate consumer interest in eating out. Darden hasn't suffered the same ill effects at its value-oriented casual dining establishments, but management indicated that competitors have been increasing their promotional activity as 2018 has progressed -- something Darden scaled back on last quarter to boost the bottom line. That could eventually lure the company's patrons away to cheaper pastures.

Cooked to perfection?

There's more: Darden's performance year-to-date isn't anything particularly special. Optimistic American consumers have been spending quite a bit more money on dining out this year. Total spending on food services and bars is up 6.2% year over year through the first 11 months of 2018, according to the U.S. Census Bureau. That makes Darden's 5.7% revenue growth so far in its current fiscal year look pretty average.

Nevertheless, Darden's management and Wall Street analysts expect the company's gradual sales growth to continue. Darden expects to finish the 2019 fiscal year with same-store sales up 2.5%. Earnings per share from continuing operations is projected to come in at $5.60 to $5.70. That would be an 18% annual increase at the midpoint of the guidance range.

Darden stock trades for about 17.5 times the company's projected fiscal 2019 earnings. That isn't exactly a bargain-bin value, but it does assume Darden will deliver similar results for the next six months even as competitors in the eating-out realm are ramping up incentives to steal away hungry mouths. Given where the restaurant industry is right now, I'm being cautious with Darden -- and restaurant stocks in general.
