It's about a 10-15 minute walk from the center, but it's definitely worth it! We were instructed to order a steak at a machine (for which we got an English menu) and we ordered the 300g Yappari steak for ¥1,480. We got ourselves some nice sides (unlimited) and water (free) and then we got our steak - Wow. Deliciously tender, perfectly cooked and sizzling hot on lava stone. Seriously without a doubt the best (and probably cheapest) steak I've ever had!
