I'm also down for Five Guys.
Mert's is home cooking as far as I'm concerned, and it's good but not something I crave. Enso is good, but expensive and I don't like to do out-of-town sushi unless I'm at the ocean on a trip. Fuel might be the home to the drink and draw, so that could get really crowded.
I'll do whatever you all want, though. But please mark my vote down for Five Guys.
