ROHNERT PARK, Calif. -- The crowds have been non-stop during the first week of business at a California fast food restaurant, with a twist. It's a drive-through that is actually good for you.It is the nation's first organic drive-through restaurant. It has only been open five days and already it is struggling to keep up with demand.Hungry customers at the new Amy's drive thru were patient and determined to order lunch. The wait is really long. Some said they heard the wait was 20 minutes long.The line inside the restaurant was almost out the door, all for a chance to try organic, vegetarian fast food.Kelsea Baraga is trying a veggie Amy burger and brought her mom along to try it too."Processed foods definitely are big on my mind. My daughter keeps bugging me about going vegetarian," customer Amy Braga said.You won't find burgers or fried chicken on the menu, but you will see healthier options such as vegan Mac 'N' Cheese and gluten free pizza."The actual demand has been a bit overwhelming," Paul Schiefer from Amy's Restaurant said.Schiefer says the local company, which has been making frozen organic foods for years, never dreamed the restaurant would be such a hit."So many people have shown up and it's giving us a lot of hope that this is a concept that works," Schiefer said.Carolyn and James Wasielewski came from Petaluma to check it out.Carolyn said they came to "celebrate good food and be healthy."James is still skeptical. He had the vegetarian burrito and said, "It could be better, but it's edible."The food is sustainably grown, including the roof. Employees are paid a living wage with health benefits.If business stays like this Amy's plans to open other drive-through across the Bay Area.
