For example, Taco Bell Cantina locations often close at 12:00 a.m., and some Taco Bell locations can close as early as 10 or 11 p.m. on certain days. A specific example from a dining services schedule shows Taco Bell Cantina is open from 11:00 a.m. to 12:00 a.m. on Sundays.
If you want to know the closing time for a particular Taco Bell near you, checking that location's hours directly via Taco Bell's store locator or contacting the restaurant is recommended. So, as a general guideline, Taco Bell typically closes around midnight, but local times can vary.
