Dinker's Bar and Grill is known for its drool-worthy Haystack Burger with American cheese, honey-smoked ham, and a fried egg on a delicious grilled kaiser bun. Make sure to order a side of onion rings, you'll regret it if you don't. Famous for their beer and burgers, Dinker's has been an iconic Omaha institution since 1965. They still make their burgers the old-fashioned way with an ice cream scoop and hand press.
