UANL Teatro Universitario is the university concert hall used by the UANL Symphonic Orchestra, one of Monterrey's main classical ensembles. The orchestra usually presents several short seasons through the year, with programmes that make a good evening stop if you want something quieter than the city's bars.
It sits on the university campus, so check current schedules and access details before crossing town. Some performances also move to Teatro de la Ciudad in the centre.
