text: Derald's is a popular fast food place and they do business from a small truck. They are located near Mathews Ave and Green St and another is at Mathews Ave and Springfield. Burgers are made-to-order and they are cheap.The fish burger (only on Fridays) is one of the best I have had but I don't think they use really fresh fish. It tastes really good with tartare sauce, onions and vinegar.
