Columbus, Ohio: Test market of the U.S.A.

In this case, the whole restaurant was a test. At Piada, they'll stuff a grilled flatbread with all the Italian delicacies as it can hold.

Chris Doody opened the very first Piada less than two years ago. Now there are six.

"Are these people with discerning palates, would you say?" Smith asked.

"Absolutely," he replied. "People are very sophisticated today. Columbus is a sophisticated market."

"Are you guys making money?"

"Yup, yup, so far, so good," said Doody. "It's no fun if you don't make money in the restaurant business."

And when we were there, the line never seemed to end. Expansion plans are in the works.

And then there's the Giant Eagle Market District, which could be the mother of all grocery stores. You can find cactus in the endless produce section. The butcher shop has every kind of meat, including rattlesnake and python.

"Consumers can come in here, with the same shopping trip that they pick up rattlesnake they can pick up their Cheerios," said Giant Eagle senior vice president Brett Merrell. "You have been longing for that for years, correct?" he laughed.

"Are there people who come here and are just overwhelmed?" asked Smith.

"There are - but they love to be overwhelmed," he said.

Merrell says the Pittsburgh-based company uses this location as a lab for things like nutrition labeling and frequent shopper perks.

And there another little idea they're testing in Columbus: They'll sell you wine in an actual glass, so you can drink while you shop. Of all the concepts they're trying out at this store, they tell us this is among the more popular.

"We love the Columbus market, the Columbus people, and we think this is a really good testing ground about what success will be, and so far it's worked very well," Merrell said.

"There are those who might look at this and say, 'Does the world really need 15 different types of malt balls?'" Smith said.

"No, a person may only need one type. But you know, the exciting part is, people can choose what they want," Merrell said.

And what they choose in Columbus today - may very well determine what YOU will buy tomorrow.

Smith asked Bruce, the "guinea pig," if he feels he has superior taste to the rest of the nation, and is that why they call on him.

"I don't know about the rest of the nation, but I have superior taste," he said.

And his wife concurred, for after all, "He chose me!"
