This place has the unique "enomatic" machines, so you can sample many different wines, in 1,3 or 5 oz pours. You buy and charge up a card, then use that card to purchase your pours from the machines.
The decor is really great and they offer a full bar in addition to the "sampling" wines. The only downside is that the wine selection/variety can vary pretty substantially. It can be pretty pricey too, where $50 on the card only gets you lightly over a handful of interesting tastes. For the folks who want to try premium wines that are expensive for a bottle, yo can do that here, but the tastes aren't cheap either.
