Oh boy - I love a hint of liquor in my blood when I'm shopping.
Von Fass' oil vinegar selections are great. My bf and I are particularly fond of pear vinegar and cherry balsamic. The sampling makes the shopping experience really fun.
The liquor variety is what excites me the most. The apricot liquor is ohmygod delicious. They also have nice scotch, calvados, absinthe, and bourbon. If I had the money, I would love to take home all the casks.
The speed of service varies depending on the staff. Most of the time, it's great, but once I encountered a miss-turtle-pace. But that shouldn't deter me from coming back.
