Damn! It sure is! Thanks very much for finding that.
This what you're looking for?
That's on the shelf at the Sellwood/Moreland liquor store. It also appears to be at the 1st Ave shop downtown.
For those who don't know, the ONE thing that doesn't suck about the OLCC is this site: http://oregonliquorsearch.com
BTW, if you do a search for 'amaro nonino' this doesn't come up, as of the last few minutes. I've been checking for weeks now.
That's a different Amaro than the one called for in the recipe - Amaro Nardini.
Generally I use the shortest descriptor I can. I.e. each one of these will show up individually if you type in Nardini or Nonino rather than Amaro Nardini or Amaro Nonino
I do think the question up thread about anyone actually eating at Imperial was valid.
