MM - so sorry I haven't been around of late to give you info on the restaurants. Rl mini-crisis (now resolved) intervened
. Great news about your dad 
Here is a list of restaurant recommendations:
in the marina we ate at
Tomata
Macaroni
Vosporus grill (can't bill to room, cash only, there's a cashpoint in marina btw)
Psarrr.....something Taverna
all of above v child friendly and v good food.
We also ate at Water Restaurant in Sani Asterias hotel - more formal/fine dining. Very nice but more ££££ and adults only.
Friends recommended the See You restaurant if you like sushi - DH allergic to shellfish so we didn't try.
We also did the Greek night in our hotel - Porto Sani Village - Wed night? Highly recommend. V child friendly - live Greek music which all the toddlers can dance to (!!) and dedicated children's play area with supervisor in one corner of dining room.
HTH, sorry to rush in and out but felt really bad for not being around. hope you have a great hols.
Carciofi - have a great hols.
Cake - welcome home
