We've been to Pappafo a few times. In the summer it is the most delightful place to eat out - if they let you. On our last visit on a warm August evening the staff declared it to be too cold (for them) to serve us outside. Eating inside does not always have the same appeal.
Foodwise, the antipasta is excellent and the pizzas can be wonderful (depending upon who is at the pizza oven) The gourmet pizzas are expensive but very nice for a change. If you don't want pizzas there is a full on menu of elaborate dishes, but sadly no nice salads. The service is good and the staff are lovely.
