Oh so disappointed.  I had not been back to the Penguin since it closed. Loved the old Penguin:  the food, the servers, and the atmosphere.  Took my Dad there all the time because he loved it - especially the single blockburger, fried dill pickles and the onion rings.  We were going to try the Diamond, but as we drove past the Penguin, my father noticed the Penguin was opened again and wanted to go (despite there being only 3 cars in the parking lot during the noon hour on a weekday.)  So we went to the Penguin.  A mistake.  Unlike the old Penguin's burger that was moist, not over-worked, and tasty, the hamburger was bland, tough, dry.  The onion rings were tasteless - some salt (not a lot) in the batter might help bring out the flavor.  And the fried dill pickles that were so good at the old Penguin were tough, dry, and tasted nasty - like fishy fried fish.  There were only three other tables with people.  The staff was ok, but not particularly friendly and seemed more interested in attending to themselves at the once crowded bar. What food they had to serve, gathered waiting in the kitchen.  Really very sad.  I hope they can get their act together.
