Maybe the worst service I've ever experienced at a restaurant... ever. Food was just mediocre, but the service is what turned me off. I guess they assumed that my friend and I were "clueless white people," but little did they know, my friend speaks fluent Japanese and translated the fact that they were blatantly calling us stupid when we experienced problems paying (card was declined a couple of times).
Message to owner: think twice about who you hire and how you train them. There was no reason for us to feel uncomfortable for something that wasn't our fault. I will never, ever, ever be returning and I'll be advising my friends and family against it too.
