The acai bowl trend has hit stride in bigger markets like New York and Chicago and splattered retail districts and neighborhoods in California, Hawaii and throughout the country. And now its presence is growing in Louisville. Luebab Ahmed and his business partner, Aiman Ali, quietly opened Lueberry Acai at 808 E. Market St. in the NuLu neighborhood late last month in a small 1,000-square-foot space near Please & Thank You. The name is a twist on Ahmed’s first name, the word "blueberry" and a nod to Louisville as well.
