Vista Brewing this Saturday will began serving at its east-of-downtown cafe and tap room — a soft opening happening just in time for the kickoff of San Antonio Beer Week. The Austin-based craft brewer’s new venture, located at 125 Lamar, Suite 106, joins Boxcar Bar, Burleson Beer Yard, juice spot Southwest Elixirs and tropical cocktail oasis La Ruina in the development at the intersection of Lamar and Austin streets. The cafe will focus on menu items prepared with sustainably and locally sourced ingredients, according to Vista honchos.
