No two people can agree on what makes the perfect London pub: for some it is all about the beer - which they can indulge at places like the Euston Tap, where craft beers abound - while others are looking for entertainment - which can be found in the form of live music around the city on a nightly basis. Some people won't go anywhere without their beloved dog and others are looking to meet that special someone at one of London's multitude of singles nights. On top of all this, it probably should be local and the people inside should fizz with beauty, charm, wit and intelligence, no bar-room bores here please. A special offer here and there wouldn't go amiss too so maybe Groupon can help you out with your decision.
