Time Out says
One of Konzum's new superstores stands beside a car park near the ferry terminal and the bus station. Super Konzum offers pretty much everything, electrical goods as well as foodstuffs, with a bakery, butcher's, deli counter, and rows and rows of quality Croatian wine at knockdown prices. If you need to do a major shop for the week or knock together a budget barbecue, this is the place to do it. It's a short stagger to the bus stop for the Old Town – you'll have to change at the next junction for Lapad.
