The bodega offers a wine tasting via an automat. You get a card and choose the wine you want and how much of it. That may seem a little soulless but it is flexible and, for walk-ins, perfect. You taste in your time, without hard or even soft selling by the staff.
The prices are adequate, so that you can easily taste half a dozen wines for less than 10 USD.
The Malbecs and the Tannat I tasted were, for their individual price range, excellent, and I hope to find one if them at home.
