For us the worst is Crystal Palace. Easily the worst food we have had on any trip and bad service to match. We have ate there twice with the same result. Last time we were on the DDP and the waitress brought our drinks and never came back to clear plates or bring refills but she managed to bring the bill with a $35 tip included. Had to talk to the manager and he eluctantly dropped it to $10 which was still about $9.99 to high for the service.
One of our worst meals last week was chef mickey's dinner. It has always been of my kids favorites but the food was not good.
So I will amend mine to say that my worst dining experiences in the world have all been at the ABC Commissary, which I have tried three times now and will never go back to. I forget what we had the first time, but we tried the chicken and the fish the next two times. Greasy, no flavor, and the place has no character. But we were kind of up a tree when we couldn't get in anyplace else that was indoors on a hot afternoon (we didn't want pizza at Pizza Planet, which we usually do). Any recommendations for CS indoors on a hot day in DHS?
