As a celiac I pretty much never eat out! We had a wonderful experience! When we came for the weekend I was pregnant and dealing with a lot of nausea and the gal there was so nice as we changed our order from here to to go. We came back the next day and she asked how I was doing. The food is amazing!!!! So nice to have an all gluten free place where I can have peace of mind that I won’t get sick. To have waffles?! And toast!? So amazing!!! We went 4 times over the span of 3 days! We will definitely be back!

As soon as you walk in, you are greeted by a beautiful and smiling host/server. Martina makes you feel at ease and she is very knowledgeable on the menu. She is very attentive and you can feel a very calming and positive energy in the cafe due to her positive nature. My sister and I tried the granola bowl and it was absolutely delicious. Wow. The yogurt was creamy and rich. The granola was not too sweet and tasted very fresh. I had the “make you own” smoothie and I substituted milk for coconut water due to my dairy allergy. My smoothie was definitely and without a doubt the best smoothie I have ever had. Not only was it very healthy, with no added sugar, but it just tasted fruity and very fresh. It’s almost hard to describe the flavor because it was too good. I also loved the fact that I could feed both the smoothie and parfait to my daughter without any worry that it was unhealthy. And Luna sure loved it! We loved the cafe and wished we had been there sooner. Definitely our favorite cafe in Door County and we will be back. Thank you, Martina, for an amazing experience and for taking really good care of us.

We had the most amazing breakfast! If you are in Door County- this is truly a must go. It’s a minute off the beaten path- and in a good way. It’s so cute! The chai teas- hot and cold- were delicious. Smoothies were yummy.

Tucked away in the country walk shops, is this gluten free zone. The spicy marsala Chai was a delicious crowd pleaser, so I highly recommend it. The service wasn’t fast, so don’t be in a hurry, but the staff was polite and the food was good. We ordered an array of options and all were very good, even for the gluten tolerant.

Visited this morning while on vacation, and it was wonderful to get a steaming hot latte and the most delicious avocado toast. My daughter loved the homemade granola on her yogurt. It is a nice healthy recharge while we haven’t been eating the best this weekend. I wish I could visit daily!

My husband and I ate here on the first morning of our trip and was so good we had to come back the next day! Zero Sum is a great place to eat and enjoy company. Martino took great care of us and she is an amazing chef! It can be so hard to find gluten free food you can trust, especially while traveling. It was perfect to enjoy a meal knowing there is no chance for cross contamination. We already cannot wait to come back on our next trip!

Seldom have my wife and I visited a place that offers such fresh, unique, and delicious foods, that are guaranteed Gluten Free. The staff were extremely kind and friendly. I highly recommend this for anyone looking for high quality gluten free food, or healthy, delicious eats/drinks.
