Different, in a nice way. The pineapple adds a different twist to the "typical" Margarita profile. It was quite enjoyable. Pineapple was subtle but not overwhelming. I also added the bitters to the mix instead of adding it to the top and it was nicely balanced. Highly recommend it.
Living in San Diego, California, we have a lot of different margaritas available. I gave this a 5. It is unique and very flavourful. While it is strong, the taste is not overwhelmed by the tequila. The dashes of bitters on the top was OK, but after tasting, we mixed the bitters into the cocktail, as there was too much bitters flavour in the first sip. After mixing, it was very well balanced.
