Delica rf1 in San Fransisco Ferry Building is a great place for a bite. I tried the Potato Croquette, Sushi rolls, Tuna Tartar appetizer and Miso Soup with sparkling wine and all of it was delicious. The portions were not too big and the flavors well well balanced. Even the fired potato croquette wasn't overhwelmin. This is a great place to nosh.
