Having been coming to this restaurant for years, I've noticed a significant improvement since the beginning of this year. No more long wait times, and the staff is much more welcoming. It's now a pleasure to come to McDonald's from Héric.
I ordered sparkling water, but it tasted like old orange soda. We pointed this out to the manager, who simply replied that they probably needed to change the filters. He then refilled our glass… which tasted exactly the same. No refund or alternative drink was offered. Very disappointing.
Fairly fast service, friendly waiters (especially the redhead with glasses), food of fairly good quality, that said, weekends are quite busy, avoid peak hours.
