Would anyone know if there is a large supermarket in Novigrad? Is there a Lidl/Aldi nearby. Is it expensive to eat out? We are going on a 1week self-catering holiday there next week.
You are in luck! :) There is a Plodine and Mercator but there is no Lidl.
Cost of eating out is relative...fresh fish is indeed expensive and is mostly sold by weight so be cautious when ordering. Three courses for two people can easily be up to 500-600 kn (80-100 euros) or more; if meat, about 20% less. However, you can find delicious pizza, pasta, risotto, etc. for 10 euros, give or take. The Novigrad area is known for its fish and seafood so if you feel indulgent, you can eat very, very well. :)
we are also there next week, would love to hear about any information you get, maybe see you wandering around
I hope I don't meet you wandering around!
