Corfu Old Town - Self Guided Food Tour?

Seeking advice on a 2 hour self guided walking tour of unique foods to try in Old Town Corfu.

I have heard of Taverna Ninos, Taverna Averto Cafe, Diporto, Pane e Souvlaki as places to check out. Would like to sample pastries, local Greek cuisine, some wine, kumquat liqueur.
