<p>If you’re not a big meat-eater, and if your d’s rehearsals are in the theater district, just walk over to 9th Avenue and you can find all sorts of great ethnic eats, cheap, in very simple surroundings, a real NY experience. Try Pam Real Thai at 49th St. and 9th Ave or Mee Noodle at 53d and 9th. Have fun.</p>
