There are only a few cinemas in Oaxaca city, you can choose out of three different Cinemex cinemas…read moreand this one Cinépolis. Although Cinépolis is quite a bit more expensive, it offers more movies (such as the suicide squad :p) with bigger screens and better sound quality.
The service has always been really good and quick. I think this cinema has about 12 screens and offers movies dubbed in Spanish but also subtitled. Of course the originals are way better to see than the dubbed versions.
You can buy your popcorn, nachos, other snacks and drinks before you enter to see your movie. They have different packages but actually they are not cheaper as you would think, if you buy the popcorn, drink and extra snack separately they cost the same.
