Does anyone know the recipe for the lemon drops at Amber in Seattle, WA?

I went to Amber with someone I was dating this past summer and ever since we've been obsessed with either finding or making the perfect lemon drop and nothing seems to compare. We both live out of state so just going to Amber for lemon drops isn't an option. I'm flying to the East coast to visit for Christmas and bought him some silver martini gl and drink shaker ornaments. I'd love to give him those and the recipe for the actual Amber lemon drop as a Christmas gift. We've found the ingredient list online but the recipe is nowhere. If you know it I would be very grateful to have you share it with me.
