Hands-down, this was my favorite bar in Vina del Mar and probably Valparaiso, for me and my friends at least. Everyone is entitled to their own opinion I suppose, but this place was off the charts. We'll start with the service. We went often enough that they got to know us, and they were always extremely hospitable. The prices could be expensive sometimes, similar to the United States, depending on the drink, but happy hour always had reasonable prices. You can expect to pay around $3-6 for mixed drinks and $2-4 for a beer. During Happy Hour the drink prices drop to around $2-5 for everything (and Happy Hour lasts till about 11 in Chile since everything gets started so much later). They do have wide variety of beer and mixed drinks. The atmosphere was more relaxed than most bars. They even have a side room with couches if you get there early enough to claim them.
The real catch was the live music on Friday nights that started around 10-11, but that was chilean time and sometimes they just run on their own time so it could be later. Every Friday night they had a couple guys playing acoustic music. Since Chile is somewhat obsessed with classic rock music, they played a lot of Led Zeppelin, etc., which was nice. A typical night for us consisted of arriving at around 9-10 at night, early enough to claim our usual side room with the couches and candles. We would play cards or chat about the week's adventures for awhile and then the real fun began. We loved the acoustic music (one of the musicians was actually my host brother while I studied abroad). We would sit and listen for hours waiting to hear that one classic rock oldie that had been running through our head for the past week. By the end of the acoustical show, it was around 1 AM and things were just about to get rolling in the rest of Vina and Valparaiso so we would be on our way. Barrilete is a good bar for anyone looking for a fun night out, college-age to married couples. So if you are looking for a hang-out spot that is relaxing and has decent prices, an awesome atmosphere, and amazing music, you should definitely check it out.
