I have been going to Otto's on Memorial for many years and have always been satisfied with the food and service. However, I just went to the tunnel store downtown and ordered to go. When I got to the office and began to eat lunch I could not eat the potato salad which smelled spoiled and was warm. I also had to talk to the food service people three times before I received all the items I had ordered. I am very disappointed because I had expected to have a good experience.
