Can't be certain what the store is called,(Cortinas Gregorio?), but you will find it if you follow the road to Garrucha (from Thalassa), and opposite the row of shops which includes Smith&Hutton Butchers/Beer Emporium/Angus&Hereford Argentinian Steak house etc., is another row of shops (on the right above the road). The shop is there between the kitchen shop and Atlas Estate Agents. The shop sign is a black background with red lettering.
Hope this is of use.
