K&O italian mini mart is placed on near colombo-batticola (Ratnapura-Colombo A4) highway. It has many more italian food,cosmetics items and beverages.. And the price is low than other super markets. They supply online goods delivery service too. So you just need to do is call them or visit there facebook fan page to order. Highly recommend for tourists and locals..
I was surprised to find an italian food mart in Rathnapura. Prices are very reasonable
