This drink comes from CO'M a Vietnamese Grill in Dunwoody Village in GA.  It's one of Marlo's favorite haunts....and we can see why, with drinks like this!
CO'M Crusta:

1 oz. Bombay or Bombay Sapphire
1 oz. Domaine de Canton (French Ginger Cognac) 
1/4 oz. fresh lemon juice
1/2 ounce Blue Curacao

This drink has a warm undertone and it is super refreshing. The ginger gets you as an aftertaste and it is wonderful.
