Gus's has quickly become our go-to breakfast place in Sun Prairie! The service is friendly and usually pretty quick.
It's a 50's style greasy diner, but there are some decent breakfast options if you want to stick to healthier choices. Their omelettes and scramblers are great - the greek omelette is our favorite! If you don't want the extra calories, they are very nice about customizing the order to your preferences.
Order off their breakfast menu - their lunch/dinner options haven't impressed us.
