Review for The 101 Casino Review For The 101 Casino Google User Jul 28 '10 at 21:41 We have eaten at the 101 two times now and we are so happy with the food ( which is very good), atmosphere, service, etc.!!! I think the 101 Casino is the best kept little secret in Petaluma!!! My mom had the filet mignon and her steak melted in your mouth!! It was an excellent cut of beef. I had the special for 10$ prime rib and it was also delicious!! You have to have the Berry Mousse!!!!! It was to die for!! View full site to comment or like
