☕✨ We're Heading to The RiverSide Gypsy Holistic Festival This Weekend! ✨☕

Looking for a fun, welcoming event where you can explore something new in a relaxed, no-pressure atmosphere? Come visit us at The RiverSide Gypsy Holistic Festival! With activities happening throughout the day and a variety of amazing vendors, there's something for everyone to enjoy.

We'll be there serving up our fresh-roasted coffee to keep you energized and offering our delicious freeze-dried candy!

Even better, the festival is taking place right across the street from our shop inside The Mariner. If you need a break from the summer heat, stop in and explore everything we have to offer. The Mariner is home to four unique stores, along with a wonderful collection of locally made artisan goods throughout the building.

We can't wait to see you this weekend—whether you're visiting the festival, stopping by the shop, or both!

We are still feeling the good vibes from this past weekend. Marine city absolutely nailed it the whole weekend!! The amount of support and positive feedback on the shop and our coffee blew our minds and we are beyond grateful to the city, the residents, and everyone else who came out and made it a memory we will never forget. While some people think our place isn't a "real coffee shop", we think we've created something more. Not just a place to get coffee, but a unique and whimsical shop with something for everyone. It's a place for friendly conversations, positive vibes, and a judgmental free place to enjoy the best coffee in town!! We look forward to keeping Marine City well caffinated for years to come!! Thanks again for all of the love and support, and as always, sip curiously my friends!! We are located inside The Mariner Theater at 430 s water street in Marine City.
