Asking Where the Bathroom Is

You urgently need a restroom and ask the nearest person for help.

Disculpe, ¿dónde está el baño?
dees-KOOL-peh, DOHN-deh ehs-TAH el BAH-nyoh?
Excuse me, where is the bathroom?
In Latin America, 'el baño' is the most universally understood word for bathroom. You may also hear 'el servicio' or 'los sanitarios.'

Está allá, a la izquierda.
ehs-TAH ah-YAH, ah lah ees-kee-EHR-dah.

SEE, al FOHN-doh ah lah deh-REH-chah. ah-EE loh veh.
Yes, at the back to the right. You'll see it there.
