I think Menorca will be a bit dearer, but it depends where you eat??

We eat in resort and pay up to 25 euros for breakfast for 4 (2 adults and 2 children).

For the evening meal i seem to recall up to 50 euros???

Restaurants tend to be a little more expensive in Menorca but I have always found the quality to be good.As you are staying in Sa Caleta you will be close to the Diskont hypermarket where you will find your everyday provisions a lot cheaper than the local supermarkets.
