Of course since Poland and other Eastern European states joined the EU in 2004 the UK has seen a massive influx of migrants from these countries. We have seen a great many shops selling Eastern European foodstuffs, and luckily for those of us who will try any beer once: lots of new beers.
I am sure this pub will concentrate on common national brands such as Lech and Tyskie, but in shops in Northampton where I live I have found such delights as Ciechanów Farskie Piwo Ciemne a very decent dunkel from Poland, Svyturys Degintas, another dark beer (possibly a dunkel) from Lithuania and Obolon Porter, a delightful Baltic Porter from Ukraine. I have obviously had tons of pretty poor pale lagers also, but at least they are new experiences. One thing that I have noticed is how cheap these shops sell the beers and that can only be a good thing.
Just as an aside make sure you read all the smart alec comments at the bottom of the article. They should give you a giggle.
