The beautiful people, the beautiful people! The answer to the question "What is Seif?" can be summed up fairly easily. It's a large nightclub at the edge of Old Town, housed in a former bank building where, currently, many of Tallinn's most beautiful people hang out listening to rather pumping house and club music while sipping on 'high-end' cocktails and flaunting their ... talents. It certainly fills a certain niche and often the parties last until the wee hours of the morning. Dresscode - to impress.
