Splash Wine Lounge
3043 University Ave, San Diego, CA 92104
This is the only place I've ever seen the wine vending machine concept. It's really neat - the 1 oz pours are enough to get a good taste of the wine and to figure out if it's something you'd like more of. Also, particularly for the expensive wines ($50+/bottle), it's much more affordable than buying a glass so it gives you a chance to try wines you otherwise would shy away from due to the cost. They even arrange the red wines in groups by cost so if you want the cheaper options, you can stick to the first group (all under $1.60). We started off with $20 on our card and wound up putting on another $20 since we tried some of the pricier wines - well worth it.
The menu is pretty limited, but when I smelled something delicious coming out of the kitchen, I asked what it was... flatbread pizza. We ordered the Spring Splash pizza, and it was ridiculously good.
While this place isn't cheap, it's not as expensive as it could be, and it's a cool experience. It was pretty empty when I went (6:30-8 or so on a Thursday night) and one person was working the bar and tables and refilling the wine - not sure if it picks up a bit later on or not.
