Brunberg
One of Finland's most famous confectioners, this family-run business was founded in 1871 and is best known for their Pusu "Kisses", or giant puffs of flavored whipped cream encased in a thin chocolate shell. Until recently, they were known somewhat politically incorrectly as "Negro Kisses". Brunberg's liquorice lakritsi is another local favorite, and don't miss the chocolate truffles either. Most products are actually made at a factory on the outskirts of town Teollisuustie 19 B, Mon-Fri 9 AM-5 PM, Sat 9 AM-3 PM, but their always-crowded Old Town shop is considerably more convenient.
In the old part of Porvoo there are lots of lovely little shops where you can buy anything from dollhouses to hand made jewelry. Many are, however, open only in the summer.
