A-little-learning-is-an-embarrassing-thing department: If you'd been standing by my side when I spotted the legend "sub & Chinese food eat-in and take out," I would have told you about "subgum." The word is a romanization of characters that, in Cantonese, mean "assorted," or "mixed," or "numerous and varied." Like another famous item on American Chinese menus, chop suey, subgum dishes often combine multiple meats and vegetables with rice or noodles.
Apparently not at Wonderful Chinese, however. On crossing the street and examining the menu in the window, I found no subgum dishes (at least under that name) but did note an entire category titled "submarine fleet." The menu is more Americanized than I'd imagined: In addition to Chinese food, served at a lunch buffet and a la carte, the restaurant makes sandwiches, too.
