"10/12/2025 Update Two visits 3 weeks apart, long wait for food, 1 hour after ordering, and waitress never stopped at table from order to food service to give us update. Owner stopped after and I let her know that servers keeping patrons updated, refilling drinks during long waits, helps. 2nd visit today was even worse. I have never in my life left less than 20 percent tip, except today. Young server, could’ve cared less about service at all. Waited 45 minutes for food, owner refilled drinks, food came partially out and not as ordered for one in our party, had to be redone. Was just watching other 4 to 5 tops that came in after us by 15-20 minutes get their food way before we got served. They had a different server, except for one, and they must have been more regulars than us. Waitress was almost rude with her silence and short interactions. Will not be returning. Original review: 6 top, great service from waitress! Not really clean, could be a little tidy up between customers at tables. Safety issue with extra chair blocking exit. Chairs stacked by our table. All of that honesty out of the way, Food was excellent! I had a breakfast, bacon eggs, hash browns and toast. Other orders were cinnamon roll french toast, sampler, french toast, eggs benedict, all delicious. Will eat again, just might make sure chairs not a potential safety problem."

"This restaurant unfortunately did not live up to expectations at all. We were greeted by an unfriendly face when we first walked in. The restaurant is very cute but also dirty. Our server was very friendly. Someone from management came over and checked up on us before we got our meal with a little chit chat, which was pleasant. She informed us all the food is fresh and hand made daily. We ordered chicken noodle soup, pork tenderloin sandwich, chicken nachos and hot fudge brownie delight. The chicken noodle soup tasted tangy, like vinagre and the chicken appeared very much like the canned chicken from Walmart. The pork was paper thin with a thick fried breading and tasted 100% processed and fake. The nachos sadly were even worse- rubbery chicken, dry beans, and unappetizing vegetables. The brownie tasted spoiled, very low quality Walmart ice cream and more than half the dessert was whipped cream. My spouse and I both got home and had a stomach ache. We really wanted to love this place, but so far this is the worst restaurant in Casper and would not recommend it to a friend that enjoys quality food."

"I had the pork cutlet sandwich and onion rings. The sandwich is HUGE and so amazing. The onion rings were popping hot and tasty The cherry pie was also good I highly recommend stopping here"
