After eating one of the best veggie burgers I've ever had at a Red Robin in Center Valley, PA, I was extremely excited to go to Red Robin at downtown Summerlin because it was close to my house. I told my family it was going to be great, and convinced them to come with me to show them how good it was. When we got there, the wait staff was very friendly and I was super excited to get my prime chophouse veggie burger. While other tables were seated and served, my table waited 45 minutes before we got our food. When the burgers showed up, I forgot about waiting because I was so excited to eat! When we got the food it was extremely disappointing. The burgers were missing ingredients, and they just did not taste good. I'm so upset, and I hope the management improves this restaurant. I had really high hopes that it would be good, now I'm just sad and disappointed because I'll never have a veggie burger like I had at another red robin, close to home. Please fix your burgers.
