Pinche Taqueria, 333 Lafayette St.
This tiny Mexican import serves carnitas and al pastor tacos ($2.95) that are way better than you'd ever imagine finding in Noho (available until 4am Wed-Sat).
Tuck Shop, 115 St. Mark's Place
The filling-to-cost ratio on these savory $5 Australian meat pies (choice of ground beef, lamb shank and more) is out of this world, but the tasty $3 sausage rolls might be an even better deal (open until 2am Mon-Thu, 5am Fri-Sat).
Fette Sau, 354 Metropolitan Ave, Williamsburg
Sure, you'll have to pop in a little before last call (it closes at 2am), but the $3 pulled pork sandwiches make it a worthy pit stop.
M Noodle Bar, 549 Metropolitan Ave, Williamsburg
After boozing at Union Pool or Barcade, head to this casual noodle bar from the owners of M Shanghai Bistro until 6am for hearty dishes like roast pork noodle soup and lo mein for around $8.
Woorijip, 12 W 32nd St.
Most people know this place as a Midtown lunch spot, but the reigning king of cheap Korean food actually stays open until 3am every night, making it a great place to score some bulgogi after a night of karaoke.
