We visited Combourg on June 29th and found this nice restaurant. The staff spoke english and were very friendly. We had 4 x children with us, and they did a child's three coarse menu for €9.50 , it was really good.
The main menu was very reasonably priced, and they had loads of choices to pick.
The house wine was good too.
No food. We have been coming there in June and September for 5 years, which is always great. Go at 6:00 PM when there are many locals. The big market on Monday is great.
