Cotija’s, the terrifically popular downtown Mexican restaurant, introduced a happy hour earlier this week that, at least initially, will run from 4 p.m. to 7 p.m. Tuesday through Thursday. The full menu will be available along with $2 domestic beers and margaritas.

Owner Leo Alvarez said today that if this goes well, he’ll likely expand evening hours and open on weekends.
