La Region, Central de Cervezas Artesanales. They have a nice selection of beers (room temperature or cold) from Tempus, Calavera, Cucapá, Minerva, Jack, Weissbier, and La Chingonería, plus a small selection of Mexican botanas to accompany your drinking.
I hope this means we'll start seeing more beer options in Narvarte, because right now, they are pretty slim.
They are located at Xola 1603. You can either walk there from Etiopia metro/metrobus by going east on Xola a few blocks, or get off at the Dr. Vertiz Metrobus stop from Linea 2. La Region is located on Xola just across Vertiz from the metrobus stop there.
