There are a million of these types of places in Vegas but this one seemed the best to me and even the best of this particular type. I had no idea that the different flavors came with different alcohols and in different strengths. It was the amaretto one that finally convinced me I needed one. Thankfully they let you sample before you buy so you can make sure you are choosing the right variety. Some are even made with grain alcohol which I forget all about since it can't be purchased where I am from. While prices are high these are quite delicious and extra shots are pretty reasonable. At this location they come in a test tube thing upside down in your drink which you pull out as you sip for an added boost. You can also get slightly cheaper refills at various places along the strip. Be forewarned though you must drink these all before getting on the bus and carrying them around does get old pretty fast once they are empty.
