Had a long day of travel and needed something to eat. Denny's has always been a spot to hit on vacation usually for breakfast. We arrived here around 10pm. Didn't realize they closed at 10:30. Amazing food as you can see from the photos, waitress was great - so friendly and had a smile on her face. She helped us pick out our food and it was done quick - fastest Denny's experience ever! Place was also very clean and quiet.

We went to Denny’s for breakfast after reading some mixed reviews, but our experience was actually quite good. The service was very prompt and friendly, and the food was exactly what you’d expect from Denny’s—fresh, filling, and satisfying. Everything came out quickly and was well prepared. A nice bonus is that if you keep your bill, you can get 15% off your next visit within 48 hours, which is a great incentive to return. Overall, a pleasant and hassle-free breakfast experience. Would definitely stop by again.

I initially planned to have breakfast at the hotel buffet, but slept through my alarms and missed the time slot, hence me coming here. It was my first time at a Denny’s restaurant, and oh wow it was amazing. I ordered the double berry banana pancake slam. Although the bacons were a bit too crispy for my taste, the hash brown and the fluffy pancakes made up for it (and trust me when I say the pancakes were so good). The blueberries were a bit sour, but the strawberries and the maple syrup sweetened the pancakes, so it all balanced out. Loved how the eggs were done, too– I asked for sunny side up eggs, and they were perfect. I went in alone, and I felt very cared for- my server kept checking in on me, as well as another server. I felt very welcomed and cared for, and am very glad I slept through my alarm. Thank you for letting me have such a great morning.
