Steak and Shake and Old Homestead I guess. Actually, there are several steakhouses in NYC that sell Kobe burgers in the $50+ range. In fact, I think NYC was where the idea started.
Close to NYC, in Jersey City. FatBurger. Juicy burgers, hot fluffy fries and shakes with mmmmm, ice cream. I should have tried InNOut when I was in Vegas and LA last year.

For anyone who's willing to spice things up a bit and go for a really good burger in a hardcore gay setting, try Hamburger Mary's in San Francisco or Las Vegas. You'll love the way those gay cooks massage the patties to create those really yummy burgers. Bon Appetit.
