Mon Ami is a great restaurant and is worth the drive if you are within 2 hours of Sandusky. It is a romantic restaurant with excellent food and an impressive wine list. Their seafood is top notch and their inexpensive, tasty wines complement it perfectly.
The Pink and White Catawba are worth trying, and I enjoy the Niagara as well. They also have seasonal offerings.
Pros: Atmosphere, Good Wine
