Hi ,
I suppose it depends where you are staying in the Port but we find supermarket Voramor excellent for a tasty take away lunch --- the food here is very good and lovely staff, it is along the pine walk. Wehave also had a quick , good quality but good value lunch in Mollies , which is on the pedestrianised road behind Paseo Saralegui, sort of opposite the bus / taxi rank. I think someone has already mentioned Al Fresco take away , we have bought the paninis , baguettes etc all very acceptable. There is also a little shop who sell the most delicious spit roasted chickens towards the back of town,perhaps someone can help me with the location I just cannot remember the name of the road. Oh and i forgot to mention Tots , opposite side of street to Mollies.
Hope this helps,Tanya
