Some of the best meat in the world comes from Argentina. This place I went to once and got the T BONE which was recommended by the waiter. He was dead on balls accurate, this is the place to go if your near the village and want some meat.

I know its crazy to start a NYC list with Brooklyn, but Peter Luger's is the best steakhouse I have experienced in the NY area. You go in and you order the MEAT. It comes on a HUGE white plate and its sizzling. Go with the fresh onion and try their patented sauce that is also amazing and sold at supermarkets around the US.

This is a CLASSY joint out of the Frank Sinatra days. Old school class with elite level service and prices. Worth it once to experience the upscale of millionaires. Dinner will cost you $200 easily if you drink wine, etc.

I have been to the one on Park Avenue and it is true elegance. Its ridiculously expensive but great to take a client or a "top place to eat on your trip to nyc" spot. Go with the steak for 2 and the potatoes au gratin.

This is the place in NYC to go for Prime Rib. If you havent had it get that and the mashed potatoes + asparagus. You wont regret it.

Go with the filet mignon, it is the best I have come across. The place is cool too in Robert DeNiro's part of New York City.

This place is very old and very good. They have an $81 hamburger that I actually tried (split with 3 others) and we couldnt believe how good it was. Its an amazing burger and a historical landmark in nyc.

This place stole a bunch of people from Peter Lugers in brooklyn and the taste shows in the product. Highly recommended if you want Porterhouse and are in midtown.

This place is known for its hickory charred meats. If your in the 50s near broadway, this is a quality choice for steak.
