Not a bar, but a very popular German microbrewery, mostly among upper-middle class Thais. It also has good food at reasonable prices, and a good stage show with many acts and fun music. It can be hard to find, but is well worth the trip. Most taxis will know this place, just ask for the "Rong Beer Yereman" (German Beer Hall) and they should understand. Reservations recommended, especially on weekends.
