A new business word is getting traction in Arizona. (No, it's not "sanctions.")

It's the term "groceraunt."

That's how Rose & Allyn's Chief Marketing Officer Stacy Pearson described the newest concept from Whole Foods Market.

The company's second prototype store in Arizona to feature such additions as a restaurant and a sit-down wine bar opened in Scottsdale last month.

At the restaurant show, attention focused on the foodservice outlet that probably best embodies the trend toward "groceraunts", Eatzi's in Dallas, recently opened by Brinker, Intl., developers of the Chilis and Macaroni Grill chains, which is doing a brisk business and is looking to expand nationally. The upscale store is part restaurant, part supermarket, and offers a variety of ready- or nearly-ready-to-eat products prepared by chefs on-site.
