A second Riverside Market is slated to open by the end of the month in Fort Lauderdale, offering more than 300 craft beers, lunch and dinner. Riverside Market South will serve at 3218 SE Sixth Ave., where The Keg on 6th used to be. The first Riverside Market opened more than five years ago at 608 SW 12th Ave., in Fort Lauderdale’s Riverside Park neighborhood. It has become a magnet for craft beer aficionados. Customers walk in and grab beers from glass coolers lining the walls and when they’re done drinking, take the bottles up to the register to pay.
