The Polish presence in "Nordeast" remains strong, including the names of local businesses that still bear the mark of the area's Eastern European population such as Sikora's Polish Market, Kramarczuk's Deli, Siwek Lumber, Sentyrz Market and Surdyk's Liquors. The Adam Mickiewicz Polish Saturday School holds classes during the school year at Holy Cross Church. For many years, the Polish American Cultural Institute of Minnesota library and headquarters were located in Northeast Minneapolis on Central Avenue, but have moved to a location in the old Saint Anthony riverfront that has an "SE" address within the Nicollet Island/East Bank neighborhood of the University community. After some years of absence, the famous Twin Cities Polish Festival returned to the area the weekend of August 15–16, 2009. The festival is operated largely due to volunteer work from the Dolina Polish Folk Dancers, a performing group whose members are deeply interwoven with the Northeast Polish community.
