Getting around the island.

We and our friends (4 of us) are coming to cala blanca on the 5th of may. We have holidayed on menorca many times and this will be our second time in cala blanca. We normally hire a car, but this time we will be using the bus service. Any advice about the service. Also any bar restaurant recommendations, for the cala and Cuitadella. We have previously eaten at Cala blanca restaurant and really liked the food a d the terrace location. 

Tia Tommo.
