The Other Burger Joint

I know I need to branch out, but whenever I go to see a movie at the Walter Reade, I go to either Angelo’s Pizza or the other Burger Joint, which is tucked away inside Le Parker Meridian hotel (118 W.57th between 6th & 7th). It’s an odd location, but the Joint really packs them in. Follow the beige curtain, look for the neon burger sign, then step into the small wood paneled room. Their meat is really good. Tonight my burger (5 bux, 50 cents extra for cheese) was perfectly cooked medium rare and really juicy. The fries are the same old shoestrings that the other Burger Joint sells, but uptown they come in a brown bag for $1.50. I believe this helps remove at least 100 calories of grease. When I save on calories like that, I have no qualms about ordering one of their brownies for dessert. They are great, but I do feel like I need to find a new place to try. Anyone know of anything as cheap and delicious in the Lincoln Center area?
