My friend and I passed Vom Fass on our way to the Canal Shops in the Venetian. We stopped in to taste some liquor and whiskey. We ended up having an excellent time! The employees are very friendly and eager to help. They let you sample as many as you want, which is lucky, because there are about 50 to choose from. My favorites were the Vanilla and the Caramel Macchiato.
We also tried some of the homemade oils and vinegars with small pieces of bread. I loved the Basil Olive Oil and the Lanzone (Phillipino fruit) vinegar. I ended up buying a bottle of each. It's definitely a fun place to stop in! Plus, who doesn't love free liquor?
