1. J.G. Melon
2. Buger Joint (Le Parker Meridien)
3. P.J. Clarke's
4. Shake Shack
5. Martell's (though it apparently has closed)
Overrated: Corner Bistro (average), Jackson Hole (awful), Prime Burger (decent)
Always a fun debate. I excluded places like '21' because as great as the burger is there, it's really a steak. Donovan's is a great place, never had the burger though. I look forward to hearing your lists.
