"Their cocktails are so unique and the vibes and atmosphere are eclectic and cozy. I tried the drop the beet cocktail which was earthy and light, and I tried the manzanita de ojo which tased like apple crisp! It seems like there is a lot going on throughout the whole week and I am looking forward to attending more of their weekly events!"

"The kellergeist is such a special little gem. It has an Eclectic community of people who are their regulars. The owners are fantastic. Matthias is originally from Bavaria and brings the European feel to his bar. His wife Jolene keeps everything organized and running smoothly. The bartenders and staff are fantastic. They serve up intricate handcrafted cocktails in a relaxed environment. You can come to the Keller guys not knowing anybody and leave with friends every single time. It is hands down my favorite place to hang out in great falls. The drinks are amazing and the environment is really something special."

"They serve the best bowls of neverending pretzels ever! And are conveniently located in the right place for food trucks and local restaurants if want other choices. The beers are cheap, cold and tasty and their mixed drinks leave your palate doing somersault of joy. Their service is always quick and full of smiles and great conversation. Walking into Kellergeist is always a treat, full of energy entertainment and feels like family. Check out the back where its spacious and homey! Met a lot of great friends here that get to know you and greet you like you've always known them!"

"My Girlfriend and I came through Great Falls back in May 2025 on a trip to Edmonton. We came here for cocktails, and were not disappointed. Our German host did not disappoint with cocktails or snacks. He is cool, and has a beautiful wife. The Public Artwork in the Restrooms was "Tha' Bomb" and made total reference to the First Amendment. I absolutely loved it."

"Delicious German beer. All day happy hour on Sundays. No food available in the winter months but they do brats in the summer. You can also bring your own food. Owner is very friendly!"
