Izakaya Seki chef/owner Hiroshi Seki will celebrate the Japanese spot’s one-year anniversary by butchering a whole 100-pound yellowfin tuna in front of guests on July 31. For three days, the restaurant will offer all-you-can-eat tuna sashimi for only $15.

“It’s just to say thank you for a good first year so far,” says Seki’s daughter and co-owner Cizuka Seki, who tells Y&H she’s only slightly larger than the fish. “He figured probably no one’s ever seen this, it might be fun.”

The demonstration will go down at 5 p.m. on the 31st, and guests are welcome to hover around the open kitchen to check out Seki’s knife skills in action.

UPDATE: Cizuka says that there will no longer be a demonstration of the butchering of the tuna due to the time involved in breaking it down. However, the deal—$15 for unlimited tuna—is still on.
