What lurks beyond the innocent façade at Plaza Liquors is a revelation: In terms of sheer volume and the wide-ranging variety, there is enough alcohol stored within these surprisingly spacious four walls to immobilize a small nation of junior ad execs. One staff person estimated that Plaza carries 600 different beers at any given time, including an extensive selection of exotic microbrews, many of which are stored in wall-to-wall coolers as singles, making them easy to sample liberally. The wine collection is equally diverse, including varieties from various organic vineyards. It's also refreshing to have knowledgeable people on staff to help discern the nuances between the myriad choices available.
