If I could give zero stars I would !This is probably my worst experience at any Denny's !!! We were constantly ignored by multiple servers before getting acknowledged or welcomed! Our server had a horrible attitude. My friend had added mushrooms to her burger, the cook missed it and we notified our server . She seemed annoyed by the fact that we told her and inclusively she seemed to not believe us. Instead of remaking my friends burger they sautéed mushrooms and just added them to her burger ... keep note ... her burger was not under a heat lamp or anything so meanwhile they sautéed mushrooms her burger dropped Temp and her burger buns became soggy!!!! The mushrooms are just thrown on top and clearly the presentation of the burger was horrible!
