Dolce Mare, located in the Ocean Casino Resort is excellent! I have been there multiple times and hope to go back again and again. It is a fine dining modern Italian restaurant in Atlantic City and has prices to go along with that. Unlike some other restaurants in Atlantic City, I believe it is priced reasonably for what you get.
Friends and family know that I have been visiting Atlantic City for decades and they often ask me for advice about various aspects of a visit to the city. When they inquire about a place to enjoy a great meal, perhaps for a special occasion, I generally suggest that they leave the confines of the casino and visit one of the local family owned spots.
