One Red Door is my go to restaurant when I'm in the area. The menu is fresh, the drinks are top notch, and you can't beat the atmosphere. It's upscale casual, meaning you'll see people in suits and ties to others in nice shorts and shirts.
The food is crafty without being pretentious, such as pan roasted walleye with charred cherry tomatoes. Pizzas come in a wide variety. There are good vegetarian options too.
Overall this is a great little spot, and a definite must try.
