Spanish to English Other Other invented word (?) or slang

I believe this has to do with "gusto", enjoying oneself or something related. I need a nice way of saying it in a text from Spain describing the setting of a flamenco show.

"Es la hora del vermut": elegante expresión y maravillosa excusa para provocar un encuentro, una inspiración, unas risas, una ‘agustera’ y un abrir el apetito sin igual.

Thanks!
