In Omaha's trendy Midtown Crossing, The Grey Plume emphasizes seasonal contemporary American cuisine derived from locally grown produce and livestock. This restaurant, open for lunch and dinner since December 2010, prides itself on practicing a no-waste attitude. Everything -- the ever-evolving organic menu, the recycled barn wood floor, -- the tabletops made of local reclaimed hickory wood -- is ecofriendly. The Grey Plume doesn't have a freezer, so everything served is fresh from the farms of Nebraska and Iowa with a few herbs grown on-site. Not your typical hamburger establishment, The Grey Plume offers a wholesome, gourmet version of an American classic. The Nebraska bison burger ($11) was tender, juicy and full of robust flavors. Coupled with a crunchy, homemade bun; mouthwatering Dijon mustard; and toppings of mixed greens, pickles and sweet caramelized onions, this savory burger was hearty and satisfying. Roasted baby potatoes with garlic aioli added zest to complete the meal. The Grey Plume's contemporary concoctions, airy ambience, attentive staff and ecofriendly philosophy made for a delightful lunch. It's the perfect place to go green without spending a lot of dough. (Prices range from $10-$30.)
