It’s hard to imagine improving upon the root-beer float. The childhood favorite masters the balance of comfort and fizz with each creamy sip.

And yet, the Lobby American Grille, the month-old bar and grill in the former Buenos Aires space, one-ups the dessert by adding a shot of Stranahans Colorado Whiskey.

The result is a deep, oaky, grown-up treat worthy of the bar.
