Sakana restaurants work under the NO RESERVATION system. You can, however, reserve a so-called VIP Area in each restaurant in the chain. Sakana - Poznan's can hold a maximum of 8 people.
We take VIP area reservations by e-mail. between 10 AM and 4 PM, and outside these hours -- only directly at the restaurant. A VIP reservation comes with the additional 10% cost of service, added to your check.
