Total restaurant industry sales are expected to increase 4 percent and exceed $660 billion in 2013, with local sourcing and children’s nutrition topping consumer trends at restaurants, according to the National Restaurant Association’s 2013 Restaurant Industry Forecast.

After increasing steadily in the last three years, wholesale food costs will continue on an upward trajectory through 2013, putting significant pressure on restaurants’ bottom lines as about one-third of sales in a restaurant goes to food and beverage purchases, according to the report.  Because of these prolonged cost pressures, restaurant operators will continue to use creativity and innovation to drive out cost inefficiencies and increase productivity to not pass along the increases to consumers at the same rate.

Among the strongest consumer trends for 2013 are local sourcing and nutrition. More than seven out of 10 consumers say they are more likely to visit a restaurant that offers locally produced menu items, and more than six out of 10 said locally sourced menus are a key attribute for choosing a restaurant. Currently, a majority of tableservice restaurants offer locally sourced produce, meat or seafood, with availability being highest in the fine dining segment.

In addition, more than seven out of 10 consumers say they are trying to eat healthier at restaurants now than they did two years ago; women more so than men (75 percent vs. 66 percent). Similarly, about three-quarters of consumers say healthy menu options are an important factor when choosing a restaurant (80 percent of women vs. 71 percent of men). Restaurants are responding to this increasing demand for nutritious options, as 86 percent of consumers say that restaurants are offering a wider variety now than two years ago.
