One of the options I miss at the Stoop is one they had a few years back where one food stall had large pans of various food like curry, chilli, other "ethnic" foods, depending on weather/time of year etc. You could get a decent warming serving of rice & curry for a reasonable price.
I also miss the old Mulled Wine stand in the winter months, where you could get a large flask of mulled wine for £12, with the flask part of the price. It was great for those cold winter months to sit in the stand with some hot mulled wine you could drink during the game to warm you up!
