Went to a Mexican diner named Castro's last Sat. It's on Myrtle Ave. across the street from a blockbuster and KFC. Food was authentic and cheap. I had chicken and mexican sausage tacos and tried some of my friends shrimp in green sauce which was also tasty. Nice authentic Mexican for those out of reach of sunset park. I wish I could think of the near cross streets but I believe it's a block or two away from Classon.
