It's reasonably priced and you get an opportunity to experience 4-5 different bars and pubs with a complimentary shot in each one and no obligation to buy any drinks. The pub crawl leaders are locals and you skip any queue's, talk to locals and get treated like a VIP in the pubs. Some nights they feature a stop at the Ice Bar which is exactly what it sounds like with -5C interior, a glass of vodka and chance to see interesting ice sculptures and meet interesting people from around the world.
