I had a great experience at Denny's thanks to our waiter, Rene! From the moment we sat down, he was friendly, attentive, and made sure we had everything we needed. He checked in at the perfect times, kept our drinks full, and had such a positive attitude the entire time. Rene really went above and beyond to make our visit enjoyable. Service like his makes a big difference, and it's the reason we'll definitely be coming back. Thank you, Rene, for the amazing service! read more

|[ f o r b i d d e n c r a v i n g s ]| Was craving pancakes after a long day of clinical so I stopped by and got the 9 grain pancakes slam-- I asked for no bacon/meat but to substitute for anything non meat, she agreed but I was disappointed to see that they simply left out the meat but didn't replace it with anything. :/ pancakes were decent but the sides were underwhelming, imo it wasn't worth the cost. Also got the tropical greens smoothie, which was okay but way too sweet (I asked for no added sugar and I'm not sure if they forgot). I've gotten this at other Denny's before and idt it was this sweet. |[ s e r v i c e ]| They were not super busy but I stood and waited for 10-15 min before I was able to order, they decided to check on all the tables and talk to another customer for awhile before acknowledging me just to tell me they'll "be right with me" before having me wait more. It was odd. Parking lot out front was easy though. Ambiance is your usual Denny's. Not sure I'd be back, it's gotten too pricy with small/underwhelming portions, and menu options lack more healthy items. Hoping this changes though! read more

Not a fan of Denny's but we were staying at the hotel next to this place and wanted dessert. Upon entering the employees seemed like they were very busy but there wasn't many customers. But who knows they maybe had a short cooking staff or phone orders. We were seated after a short wait. The table was a little dirty but we just brushed it off. It took a while for our server to come but when she did she was very nice but hard to get to our table. Our order consisted of just desserts, brownie sundae (brownie was a little hard) and the Apple ice cream thing (could have used more crust, isn't that what we always say). We waited a while for our check and to go order. Once it arrived we left cash on the table and left. read more

I had a wonderful experience at Denny's thanks to our waitress! From the moment we sat down, she was warm, attentive, and had a great attitude. She checked in on us at just the right times without being intrusive, made sure our drinks were always topped off, and had a genuine smile throughout. She made what could have been a regular meal feel like a really enjoyable outing. It's rare to come across someone who takes such obvious pride in their work. She's a true asset to the Denny's team -- we'll definitely be coming back, and it's largely because of her! read more

Good Morning Denny's! Yes it was - good food, good ambiance and good service. I always say good customer service makes a difference especially early morning! I've been to many Denny's from the east coast to the west coast of the US. This one heads the list. Early Saturday morning was a quick sit down and order. Service was amazing, and waitress and who I believe was the supervisor were on top of service - coffee cup never empty. Many ppl, from all walks, young, older, military, someone with a Trump hat and shirt - very nice person (was courteous and respectful - opened door for us). I'm not a Trump fan but can accept ppl with their right to choose. it appeared that everyone was having a good morning. Maybe it was the place!!! Would recommend this place 110%. read more

I don't even know how this restaurant have so many five star reviews I went in Wednesday night and had the worst service. it was like 4 waiters and only 1 was taking orders which it was an older lady The coffee tasted so bad and old and the food even worse. Don't even check up on you or nothing . And last night I made an order in DoorDash the same location a my food didn't even have utensils or napkins! I was staying in the hotel so didn't have utensils with me and ask for no cheese and got cheese on my order they need more attention. Have gone to several locations and this one has been the worse read more

Haven't been to Denny's in a while and we came in one night a few days prior to Thanksgiving. We were seated quickly and our server was very attentive. We were quite impressed by the updated menu and Thanksgiving options. We tried the turkey dinner which really tasted like Thanksgiving. The turkey dinner had really good flavor - was not lacking anything at all and largely portioned. We alslo had the nachos as an appetizer. Tasted kind of like 7-11 nachos which I love so this was a win for me. Lastly was the country fried steak which was also very good. The paired pancake was soft, buttery, and fluffy. We will be back. , read more
