Hing Loon is one of the best restaurants in the ID. The people are extremely nice, and the food is wonderful (mainly Cantonese). Try ordering from the many, many signs on the wall, or use the menu. Some items of particular interest:
(1) The wonton soup broth is out of this world, and the wontons are very good too;
(2) Beef chow udon with black pepper is spicy and unusual;
(3) any of their clay pot dishes, such as eggplant and salt fish hot pot.
