Oriental Noodle Shop [135 E. 45th St. (bet. Lex. and 3rd Aves.) 212-697-2353]
I wasn't sure whether or not to include this place, but then I realized that I needed to provide the working classes of midtown with more lunch options. This place doesn't exactly reinvent the wheel, but it does provide solid, cheap Chinese food very quickly. So don't expect anything high class, but you should get your money's worth.
