Welcome 


An Aquarium Restaurant

The original Fin Inn Restaurant opened May 8th, 1981 - A Family owned business with only five tables.  Its founder James L. Sieb moved to Grafton after returning home from serving his country in the the WWII.  After almost forty years of working as a commercial fisherman, James gathered local limestone rocks and creek rocks from local waterways and built the Fin Inn.  Every stone in the building was laid by him.  Today the Sieb children continue their father's legacy - offering seating for 125 guests, four 2,000 gallon tanks and table side viewing at 21 tables and a wonderful menu.


The aquariums have many types of fish native the Mississippi River.  We also feature different species of turtle, including the Loggerheads, the largest weighing well over a 100 pounds and over a 100 years old.


In addition to 8,000 gallon aquariums - the Fin Inn Gift Shop is very popular with our visitors.  

We have a full menu that includes several kinds of fish, steak, chicken and seafood and for a variety, turtle soup and homemade desserts.
