On an unassuming street in the heart of San Diego sits an unassuming brewery. Thorn St. Brewery, on Thorn St. oddly enough, presents itself as a quaint little tasting room. As you walk in the front door a moderately sized bar immediately greets you. A couple of bar-height tables are to the left, and a cozy nook to the right houses another small seating area. I liked the look and feel of the place immediately. A tasting flight of 8 beers was reasonably priced at $6, which made me even happier. The beers were good, each sticking to their respective styles nicely. I liked the Belgian Strong Ale a lot, but found the American Strong Ale unmemorable. I really liked the IPA, which was very smooth. Their Chili Pale Ale was very balanced, with no heat at all on the tongue, but a nice warm finish in the back of the throat. Not a huge fan of Stouts, I liked their Stout better than their Coffee Stout. Both were similar, but the addition of coffee to the latter made it a bit too bitter for my palate. As I was enjoying my tasters, I kept seeing people come through the front door, but the room wasn't filling up. Finally I noticed that a lot of people were going through an unmarked door next to the restrooms. I started wondering if there was a patio or something that I wasn't privy to. Chris, who accompanied me on this excursion, ventured through the mystery door to see where it led. Assuring me it was something I needed to see for myself, I ventured forth. Was I ever glad I did! Through the door and up a small set of stairs opened up to a huge room which included a nice brewing area, an additional bar, plenty of table and seating areas, and even some toys and a play area for the little ones. The place was abuzz with tasters being enjoyed, conversations being had, and kids scurrying about. The vibe was comfortable and laid back. Had I not been paying attention I could have missed the best part of this brewery, other than the beer, of course. I will definitely be back here again, possibly with my family. If they keep their beer consistent and the atmosphere friendly, this unassuming brewery will continue to call this unassuming street home for quite some time.
