We were visiting Concord and decided to visit the Old Europe based on their menu. We weren't disappointed with the food, but the service was negligent. The restaurant was fairly slow and it took 10-15 minutes for someone to come to our table for a drink order. We were ready to order dinner, but the server would only take the appetizer order.
The appetizer arrived about 20 minutes later and dinner arrived about a half hour after the app was cleared. Al told dinner took two hours for just an appetizer and entree. At that point we had enough and skipped coffee or dessert. The food was excellent, however based on the frustration with service and speed I would only recommend this if you want a very leisurely dinner.
