What are some of the more popular cocktail lounges?

Please provide me with some more context! To give you a good list of popular cocktail lounges, I need to know:

* Where are you looking for these lounges? A specific city, region, or even country?

* What kind of vibe are you looking for? Elegant, trendy, speakeasy, dive bar?

* What kind of cocktails are you interested in? Classics, craft cocktails, signature drinks?

* What is your budget? Are you looking for high-end or more affordable options?

Once I have this information, I can provide you with a list of popular cocktail lounges that meet your specific needs.
