It was a really worth experience! My friends and me had a really pleasant and funny tour with our guide Darren, around Berlin and some of its historical pubs. There, we could try historical Berliner beers, even tried by Napoleon and beers tastes that I had never tried before. This was together with backgrounds on important history events that contributed to shape the city, as well as history on the beer varieties that we tried. Also Darren made us feel as we were just in a very familiar well-known group of friends, so we enjoyed very much the nice, funny and relaxed atmosphere! It's very worth to spend a nice time with friends and learn more on the beers, "Kneipen" and on Berlin itself at the same time. Darren is a very well prepared, friendly and witty guide!
