It was a brutal summer for Darden Restaurants (NYSE:DRI). The company saw profits tank after customers shunned its flagship restaurant chains over the past few months.

Earnings fell by 38% at Darden overall, as Olive Garden booked a 4% dip in sales and Red Lobster saw a 5% drop. July was particularly slow: 8% fewer customers packed into booths at either of the national chains.

Here's a look at the recent traffic trend for these two struggling brands.

An industry trend
Sure, a lot of this drop isn't unique to Darden. Full-service restaurants have been losing market share to fast-casual operators for a while now, and that trend continued in the second quarter as the sector jumped by 8%, while sales growth at full-service shops remained flat.

Chipotle (NYSE:CMG) and Panera Bread (NASDAQ:PNRA.DL) are big beneficiaries of the move toward quicker, cheaper eating. They each improved sales by 5.5% and 3.8% last quarter, while Darden's comparable sales shrunk by 3.3%.

Menu missteps
However, Darden has made things harder on itself by pricing many of its customers off its menu. The company stumbled in its recent promotions, misreading how value-sensitive diners are these days. Darden admitted as much last winter, when it decided to retool its menu and promotions so that they "better fit customers' current financial realities and expectations."

That push toward more affordable options has sped up Darden's dip in profitability. While its operating margin almost hit 10% in 2011, it has been on a downward trend ever since.

Looking ahead
Unfortunately for Darden, things could get worse from here. The company pointed out that its sales and traffic trends in August were less bad than those of the industry as a whole, suggesting that it might be on the cusp of a recovery.

However, Darden plans to cut its workforce as part of a bid to save $50 million a year and hit its 2013 earnings growth target. While that might be a good decision for the short term, it's hard to see how Darden can improve its guest experience while gutting labor spending.

In my view, the company would be better off following something like Buffalo Wild Wings' (NASDAQ:BWLD) latest strategy. B-Dubs just started employing what it calls "guest experience captains" who are responsible for keeping customers engaged in the brand while they're in the store. Despite the increased labor expense, B-Dubs plans to have those new positions in place at all of its restaurants by the end of next year. 

Sure, Darden's falling profits are a problem, but I'd argue that its guest experience levels are much more important. It might want to look at spending more on labor, not less, as it tries to lure customers back into its Olive Garden and Red Lobster locations.
