We happened to enter Black Jack incidently, and we consider ourselves very lucky. The food is not only excellent, it is also special. Superb Burger is maybe expected (though not often found) in an American Diner but a Romanian Eggplant Caviar is a real surprise. After reading the note on the menu rack you understand why. (Photo attached). We had a lovely and interesting conversation with Virginia the owner, and Christina her daughter. Virginia is an admirable lady, and her personal story flavored for us the excellent food.
Don't dare to Miss Black Jack's if you are around Jefferson!
