This is a nice little coffee shop off Main Street in downtown Burnett. Formerly known as Unshakable Grounds, it seems the coffee shop now goes by the name of Sisters Coffee. Opening hours are 7.30am to 3pm (weekdays), 9am to 2pm (Sat), closed on Sundays. They have a Christian themed indoor seating area and offer up a nice selection of traditional coffees, non-coffee drinks and light bites. I passed by recently and was served up a very good Cold Brew, perfect for hot afternoons. Would gladly visit again based on this experience.

Stopped in when checking out the farmers market. Great coffee - I had a flat white. Great little fried apple pie, not too sweet, enough for two! Great breakfast taco. Three good reasons not to go to McDonalds! Five more reasons to come here: it’s owned and run by five sisters! Support local!

We were in town for just a couple hours of layover from the train and stopped in after lunch. I ordered the seasonal Vanilla Butter cold brew and my husband ordered the pumpkin latte. I will be craving that cold brew! In fact, we already have plans to go back and recreate our entire stopover in town. Baristas were so friendly and welcoming and the atmosphere is charming. The phenomenal drinks tied the bow on top of a great excursion.

Wonderful friendly staff. Great latte and muffin. It is wonderful see a business lift up the name of the Lord Jesus. Many first responders helping out with the flood response were here as well.

This place is awesome and was keto friendly with tons of options for a keto/low carb lifestyle! I was invited here by a coworker and while waiting for her to arrive went to order a coffee. The first thing I noticed was that there were way more sugar free options than typical coffee shops have. I was excited about the variety and made a comment about that to the cashier, who happened to be the owner. She started up a conversation with me and recommended some low carb/keto friendly options. For the first time in almost 5 years of being keto/low carb, I actually got a caramel iced coffee that was phenomenal! It was truly really delicious and I was very impressed. There was no lack in flavor or taste at all and they even let me pour my own heavy cream in to my own desired consistency/taste. The owner was extremely welcoming, gave great advice and tips on what to order and shared some great options on their menu! While I didn't order any food, I was very tempted to! She really made a point to talk to me and share her story about why having some keto options on the menu was important to them. The chicken salad sounds so good (and I believe she said was less than 1g net carbs!) and I will definitely be giving it a try next time I visit! They serve keto cookies, sandwiches, salads, and drinks and they even have keto chips! How cool and rare to find! I was impressed with the selection, quality and taste and highly recommend visiting Unshakable Grounds especially if you follow a low carb/keto lifestyle! I couldn't wait to try it out, so I had a few large sips before I even got to the table to take a photo ha!
