NEW YORK >> Red Lobster isn’t just for the seafood lover in you. It’s also for that eater in every group who just wants a chicken dish.

The chain that brought seafood to the masses is hoping to broaden its appeal by revamping its menu on Oct. 15 to boost the number of dishes that cater to diners who don’t want seafood, including lighter options such as salads. Red Lobster also is increasing the number of dishes that cost less than $15 to attract customers who have cut back on spending.

The chain, which is owned by Darden Restaurants Inc., says a quarter of the items on its menu will be non-seafood dishes, up from 8 percent. And the number of lower-cost entrees will rise to about 60 percent from 40 percent.

A lot hinges on Red Lobster’s makeover. After a long streak of healthy growth that began in the late 1980s, the casual dining segment has struggled to grow in the past few years because of oversaturation of those restaurants. People also are eating out less or opting for places such as Five Guys burgers, Panera Bread Co. and Chipotle Mexican Grill Inc. that fall somewhere between traditional sit-down restaurants and fast-food chains. Red Lobster in particular has struggled, with traffic at restaurants falling in 12 of the past 24 months.

When asked about the risks involved making such a dramatic change to the menu, Clarence Otis, CEO at Darden, which also owns Olive Garden, says: “the biggest risk would be to not change.”

THE MENU

The idea behind Red Lobster rolling out more non-seafood options is to eliminate the “veto vote,” or that one person in a family or group of friends that rules out Red Lobster because they don’t like seafood.

Since opening its doors in 1968, Red Lobster has always had a steak dish or two on the menu. If people want a salad, the current menu offers a Caesar. That’s it. But diners who aren’t in the mood for seafood likely want a little more variety. So when the chain began the revamp about two years ago, it started by figuring out how to best fill in the gaps.

“We thought, what are the areas we’re missing?” says Michael LaDuke, Red Lobster’s executive chef.

Last summer, LaDuke and his team of chefs spent two weeks in Charlotte, N.C. to test about 50 dishes in three restaurants. They wanted feedback from diners, but also from the kitchen staff on any problems they encountered executing the dishes. For example, they decided that pineapple salsa should be prepared twice a day, instead of once, to keep it fresher.

Once various adjustments to sauces and cooking times were made, the test was broadened to 40 of its more than 700 restaurants in North America. Diners who ordered the new items were given surveys to fill out whether they liked the dish, what they would change and whether they’d get it again.

One of the dishes that made the cut is a Parmesan-crusted Chicken Alfredo that’s served over corkscrew pasta; it’s for diners who want a chicken dish that’s a little more decadent. The Island Grilled Mahi-Mahi and Shrimp, clocking in at a modest 510 calories, is for those who want to go lighter.

Pork chops are on the menu for the first time. Ditto for the Roasted Vegetable Skewers, the first vegetarian entree that isn’t salad or pasta. And there are now three salads, including the Bar Harbor Salad, which has dried berries, pecans and blue cheese.

Speaking about the broader casual dining industry, Raymond James analyst Bryan Elliott says such updating is necessary for survival.

“Food is a bit of a fashion business, there’s change that evolves steadily over time,” he says. In other words, he says companies are simply putting on a “more contemporary set of clothes.”

Cee Chappell-Bates, a 50-year-old resident of Columbus, Ohio, says she’d be willing to tag along to Red Lobster with her husband and children more often if there were a wider variety of dishes.

“As a family, we’ve gone probably two or three times in the past year. But they’ve been known to go without me too,” she says, noting that she hasn’t liked the texture of most seafood since she was a kid.

THE PRICES

Red Lobster’s latest update comes at a difficult time. Since 2005, consumers have been eating more meals at home and increasingly looking for cheaper options when they do eat out.

As a result, “value deals” that were popularized by fast-food chains like McDonald’s have become more common in the casual dining industry. Applebee’s, for instance, rolled out its “2 for $20” promotion in the summer of 2008 at the height of the downturn; the response was so strong that it earned a permanent spot on the menu the following February. Chili’s made a similar deal a permanent part of its menu in August 2010.

“The consumer, it’s no secret, is financially constrained,” says Salli Setta, executive vice president of marketing at Red Lobster. “When they do go out to eat, price is much more of a factor.”

Darden, based in Orlando, Fla., has been slow to emphasize affordability at its chains. At Olive Garden, the company says the “Taste of Tuscany” promotion earlier this year was a flop because it didn’t underscore value enough. And a $1 price hike for its “Festival of Shrimp” at Red Lobster didn’t go over well either. Sales figures fell 1.8 percent and 3.9 percent for the chains respectively in the quarter.

The company’s results have suffered, too. In its latest quarter, Darden said profit rose 4 percent primarily because new locations boosted revenue. But sales at restaurants open at least a year — a key indicator of health because it strips out the impact of newly opened or closed locations — fell 2.6 percent from a year ago.

Darden has since vowed that affordable prices will play a bigger role in its marketing. During its road show of new Red Lobster menu items at 40 restaurants across the country, the company tinkered with prices to see which ones might stick; they found that $15 was an important psychological threshold.

“There’s a difference between $14.99 and $15.50 and the difference is more than 51 cents,” says Dave Pickens, the company president.

Of course, the chain is betting that there are times when customers are willing to pay a little extra: The NY Strip Steak & Rock Lobster Tail still costs $32.99. And a new “Four-Course Feast” comes with a soup, salad, entree and dessert; the meal cost $15.99.
