To Eagle Eye John, you are correct! That was one of the two, actually three hot dog stands in Chicago that served lettuce on dogs. The other two were Tasty Pup in Niles(no longer in business)and Tast-E Hast-E on Harlem Avenue in Chicago. Both joints dressed their dogs with crisp and generous fresh toppings: lettuce, green pepper, cucumber, and tomato. The veggies were so abundant, I could never eat a dog without first disassembling it. My mouth just couldn’t open that wide. They also served a foot long Polish piled high with everything. I’m uncertain if Tast-e Hast-e is still around.
