"We were in town on vacation from Kansas and chose DK Diner for breakfast because of its long history, early 6 a.m. opening, and its proximity to our VRBO. We arrived at opening, and the place was pretty quiet — which made it easy to overhear the staff grumbling (a little loudly) about a coworker. Understandable early-morning frustration, but not really something you want to hear over breakfast, especially while on vacation. It’s kind of a pet peeve of ours (that kind of behind-the-scenes chatter feels unprofessional.) Guests really shouldn’t have to hear it. The hash was awesome! It is really flavorful and unique without being too spicy. It was the highlight of our meal. The French toast was a letdown and honestly something we could’ve made better at home. The donuts, which we were most excited for, didn’t taste fresh. They were tough, a bit stale, and way too sweet. We sampled both an apple fritter and a sour cream donut; unfortunately, neither one was tasty and sadly, didn't live up to the DK (donut kitchen) hype. We’d come back just for the hash, but we’d skip the sweets next time. Seating inside is limited (it filled up fast) and parking is tight, but there’s some street parking and covered outdoor seating. Our visit was on Thursday 09/18/25"

"Cute local diner. Very quick service. Self service drinks. Had the French toast. It was quite disappointing. 2 small pieces of toast cut in half. Came with bacon but I was still starving afterwards. Toast itself was nothing special. Donut sandy was a better choice for my partner."

"What a cute little diner. Tucked away in the neighborhood with not much parking , it's still worth checking out. You get complimentary, serve yourself coffee and donuts while waiting . There's a wide variety of things to make your coffee exactly how you love it. The menu is small but filled with yummy favorites. Prices are comparable to most places now, fairly cheap I'd even say. Everything was delicious and served pretty quickly. The service was great and we will definitely be back"

"This small diner is located in the heart of Grandview, OH on the corner of 3rd Avenue. The food is pretty good, but be prepared for a wait due to limited seating. Beverages are self-serve, and there’s often a long line at the cashier when paying for your ticket. DK is known for their large size donuts but I wasn’t impressed with the donuts at all. Management needs to work on adding another pay station or fixing the QR code payment option so customers don’t have to wait 20 plus minutes to pay for their meal."

"Good food for the price. Their scrambled eggs were very delicious as well as their pancakes. Ill definitely come again!"
