Had the burger here and it was delicious. I believe someone told me it's cooked in duck fat (don't hold me to that!), but I swear I tasted the duck-ness of it—so delicious. I also loved the presentation. The burger sat tall, but not so tall that it was overwhelming to fit my mouth around. I'd go back for this.
Only complaint was that the tab for two burgers and two drinks at the bar exceeded $50. I'm not sure that I'd eat a burger as a splurge meal, but that's what it ended up being.
The atmosphere was less than impressive, as well. It felt like a hotel restaurant/bar that was trying too hard and missed the mark.
