Limoncello is good. Got to have the original Italian one tho, not outsourced rubbish. Exported ones are a hit and miss.
The one I buy (only one I can get around here) is made in Italy, but it's probably not the highest quality. Got a bit of an artificial lemon taste, they probably supplement real lemons with lemon flavoring. Still pretty good though.
I should've gotten a few when I was driving through Italy last summer ;/ Yeh, once you got the taste for the authentic one, you'll never go back.
