Low staffing m:artttttrkes for slow service. We had to sign in to be seated. There were several tables availa ble, but we still... had to wait about 10 minutes to be seated. We ordered our drinks and food right away, but waited 45 minutes for our food. Ithink with more waiting staff and designed hostess this restaurant would run faster. But my family and I were in Dennys for overan hour-and-a-half to eat breakfast. We lost so much during our vacation time just waiting Read more
