Popcorn might not be on the menu at this specific cinema, but using the pools in the renowned Széchenyi Baths until 11 pm is all-included. The Baths launched its CineSpa event at the beginning of July, and there are two more movie nights you can join. On July 20th, you can follow the adventures of Jake and Elwood Blues (The Blues Brothers). Then, on July 25th, you can peek into the alternate reality of Jack Malik, where he is the only person remembering The Beatles (Yesterday).
The films, screened in English with Hungarian subtitles, start at 9 pm. But make sure to arrive on time, as you can enjoy the pools from as early as noon. Enter from the Állatkert körút to exchange your ticket for a wristband, and don't forget to pack a pair of slippers, too.
