This is a busy treasure trove of local foods and curiosities gift wrapped or vacuumed packed for the visitor, it is supposed.
 Ikan Bandeng Presto is a special recipe that may be sampled from the menu upstairs and was a great dish although the best things to put on the plate with the fish was a bit hit and miss by the uninformed.
 The basis is milkfish which is specially precooked so that all the bones are made edible and the flavour is developed.  Pepes Bandeng and other forms of the fish are also prepared so it says on the 'net. 
 Presto was an unexpected word to see assuming it is the Italian presto and that's fitting. 
 The store is around Lima in Semarang, north coast, central Java.
