This place should really be called Mike’s Diner, but that name doesn’t sound as good, and this “coffee shop” is from a pre-Starbucks time when coffee shops also served things like grits and hamburgers. Step into Mike’s, and it feels like traveling back half a century. It’s a tiny diner on quiet corner in Clinton Hill, and it’s where you should be eating pancakes and bacon on a Sunday morning when you want to reassure yourself that New York is not getting worse every year.
