Cool vibe. Huge hot pancakes. Ate here twice in three days. Nice waitresses and vintage vibe. As well as shockingly vintage pricing as well . How they maintain the restaurant on the prices they serve is a pleasant puzzle.🧩
Very cosy local diner along Route 66 in Waynesville, MO. We went for breakfast, which said was only served till 10:45am, and got basic eggs dishes. I got the special two eggs choice of meat hashbrowns and biscuits and gravy. I got the sausage patties for my meat which were delicious. Crispy on the outside but tasty on the inside. The biscuits and gravy were the star of the show though. The biscuits were nice and fluffy and the gravy was very tasty and not lumpy. Highly recommend that. Nice big portion for under $11. Got the two eggs hashbrowns and bacon. She can be picky about the bacon but had nothing but praises for the thick cuts she got. Highly recommend.
Went a few years back and did not have a good experience. Been there a few times since for lunch and decided to go back for breakfast, big mistake. Their special is killing me 2eggs biscuits and gravy, potates and choice of meat. Great place and now this has become our go to place. Panackes are good also.
Great breakfast. The biscuits and gravy was delicious as was everything else. Fast service. Cute route 66 decor
Outstanding service. Cozy atmosphere. Great coffee. And amazing food. The biscuits and gravy, sooo good!! Got lucky and went on a bad weather day, most other days, get there early, always packed, and for damn good reason!!!
We were part of the Hot Rod Power Tour and rolled into town with a group of seven about 30 minutes before closing. Instead of rushing us, the staff welcomed us with smiles and stayed open to take care of our group. The food was great, the service was outstanding, and their hospitality made a long day on the road even better. Small-town kindness like this is hard to find and definitely doesn’t go unnoticed. Thank you for taking care of us and making us feel welcome. We highly recommend stopping by if you’re passing through town! 🚗🇺🇸🍔✨
The staff is always sweet and the service is top notch. Food is always excellent and well made. The atmosphere is quiet even when everyone is chatting at their tables. The staff always comes out with a pot of coffee to see if anyone needed refills. Everytime I've come here my belly is full and I have nothing negative to say.
We enjoyed a great breakfast date at Flo's. Busy Saturday morning but we were greeted and served promptly. Generous serving size of all the good. Veggie omelet was stuffed with fresh vegetables and perfectly cooked. We will be back.
A very good restaurant. The food was good. I had the famous Scuttlebutt. The waitress was very attentive. It seems like a very popular place. It was very busy and the place was packed. Even so, we didn’t have to wait long for a table. I would definitely eat here again when I’m in the area.
Amazing fried bologna and scratch-made biscuits! We stumbled upon this gem on our way home from 4th of July weekend, and it was the perfect Route 66 stop. We arrived around 11:20 AM on Sunday (breakfast ends at 11:45 AM), and the food came out incredibly fast. I ordered the fried bologna with eggs and hashbrowns, and it completely hit the spot. But the absolute highlight was the biscuit—they make them fresh from scratch daily, and they are absolutely legit. Fantastic food and fast service! PS it was very affordable!
