FYI - UPDATED REVIEW
10/2017: Horrible service, mediocre food!! My family & I were really excited that a Denny's opened up in a Surprise. Sadly, it was a huge disappointment. When we arrived, the restaurant didn't have a lot of people there. I thought this would mean that we would get our food fairly quickly. Not the case! With restaurants, I know it's not fast food & I expect waiting time for our food, but after waiting for 20 minutes, we had to ask for our drinks twice. 15 more minutes after flagging down our waitress to remind her again about our drinks, we finally get our drinks & our orders taken. Mind you, the place wasn't packed or busy. When we received our food, we had waited so long that we just wanted to eat & get out. Doubt we will be back at this location again. Really sad since we were looking for to a family restaurant in town.
2/2018 My Family & I decided to return to Denny's in hopes of a better experience. Glad we did! Service & food were good and a huge change from our last time there. Looking forward to returning. Good job Denny's!
