Zero Sum Door County

A truly one of a kind place in Sister Bay for healthy delicious smoothies and tasty waffles.
The owner always thinks of new delicious foods to add to the menu. Rumor has it that mochi ice cream will be available soon.

I’ll admit that upon entering the establishment I was (silently) annoyed at my wife for bringing me to some hippie non-GMO organic fair-trade vegan flavor-free place. Well thank God I kept my first impression to myself. Literally everything we tried was delicious. Waffles were phenomenal, smoked salmon was great, the coffee was excellent, and my kids devoured some kind of smoothie that was, much like everything else, superb.
I highly recommend.

Zero Sum was a good small restaurant to grab some good food. They offer good food for those who have gluten or diary allergies. Personally I didn't love my food but the other people I was with really enjoyed it.

Such a great place. Delicious! We had the pear juice, smoked salmon toast, and the apple pie smoothie. The GF toast was impressive and tasty. Grateful to have finally found a GF and overall light healthy option in the area. (I'll still be glad to eat at the other places, though 😅)

Yummy waffles, really great smoothie (I had the sweet green), good coffee and strong wifi. All around a good experience. ☺️

This is my new go to in town - amazing coffee, great service, and the food is actually fresh and healthy. Also great spot to work, whether outside at a table or inside. Don’t hesitate to visit!

I’m vegan and gluten free and it can be challenging to find great spots while traveling so I was so happy to stumble across this place. Not only could I eat but the food was INCREDIBLE. I wish I lived closer to the gluten free vegan waffles!!! Literally the best I’ve had!!!

I was so happy I found this shop. Our daughter has a dairy allergy and we needed a good place with healthy food. They have multiple types of milk that you can order, including almond milk, oat milk, etc. As well as regular cow’s milk. They have a good selection of juices and smoothies. We loved the juices we had and will definitely be back on our next trip to Door County.

Made-to-order waffles and muffins were absolutely delicious, with more options than you'd expect, from chocolate chips and coconut to mango bites and fresh fruit. Very friendly staff that you can tell takes pride in their food. And even though it's health food, it's also delicious and filling.

Highly recommended!

Stopped in for a smoothie and an acai bowl. Both were amazing. Definitely a great spot for a hot summer day. Also the best sparkling water we've ever had.... Seriously. 10/10 will be back.
