We'll be in Omaha May 5-8 attending a full-day meeting on May 6 at the Quest Convention Center. I read some old threads recommending restaurants and made reservation one night at Gorats and I would like to try the Indian Oven another night. Are there any restaurants serving healthy/organic cuisine, or grocers equivalent to Whole Foods, Wild Oats or Trader Joe's?
We enjoy outdoor activities - are there any hiking trails/bike or kayak rentals within short driving distance of Omaha?

Any input is appreciated.
