I ate horse in Okinawa. That’s the weirdest land animal they eat. They don’t do dog and cat. But they will eat anything from the sea.
It was at a place whose name translated into "The Sick Cow"
The mascot logo was a Green Cow Face…
Anyhow, under normal circumstances I would not have stepped in the door, but I had buddies who ate there often and I trusted their judgement. It was a hibachi (not the chef with the fancy knife work, tossing eggs and such) but a large round table with a small grill in the center. Special items were cooked by the staff in the kitchen, fried rice and such. Your meats, you picked your meat, chicken, beef, pork, horse, or several types of seafood, and put it on skewers to cook on the hibachi. Buffet style, but not like American buffet. You had several choices of marinade to put it in. I think there may have been some vegetables also.
Horse… I don’t recall anything special about it. Good, bad… I don’t know. It tasted like meat.
