If you are into novelty cocktail bars, Paradiso is definitely a great place to check out! I arrived…read morearound 7pm to a decently sized line; my party of 2 didn't get seated until 30-45 minutes afterwards. I did read that there would be QR code for a virtual queue, but we didn't see that option and just ended up waiting in line ourselves.
I was worried Paradiso would have a snobby vibe to it, since it is ranked #4 in the world, but that wasn't the case at all! The servers were very friendly and the cocktails were genuinely delicious. There's also a sense of theatre when they present you with their specialty cocktails. For example, I ordered the Gravity cocktail (reminiscent of an espresso martini), and our server brought it in an interesting bowl meant to mimic a black hole and also gave a little background story to the cocktail.
They provide menus in Spanish, Catalan, and English. Servers also speak English as well, so communication is not an issue. The interior is gorgeous and and had great moody lighting, there was also a great playlist on with classic pop songs. Their cocktail menu is unique and as previously mentioned, I especially loved their presentation. Most of their drinks are served in some funky cup or bowl, it was so fun seeing the servers bring out other cocktails to other tables. Overall, a 5/5 experience for me!
