As you can see, the new small supermarket at the back of Porto Fino not far from the Minimal cafe bar is now open.
Not sure whether it will generate enough business as the opening hours are very similar to Mercadona. Something like 9am to 9pm Monday to Saturday. The only difference it that it is also open on Sundays early in the day. From 10am to 2pm.
My guess is that they will soon realise that they will have to extend their opening hours if they want to generate enough trade to keep going in the long term.
