Still digesting the good food, went a few hours back, near Gion. It's a chain and they have an English website with a map, indicating 4 restaurants right in the city center. Basically all we read on Tripadvisor before going is true: it's a very good value and 90 minutes are enough. The difference between the 3 options is based on variety, but also on the quality of the beef choices. Honestly, we just couldn't order the stomach parts or the tongue, but the japanese couple next to us seemed to have leaner parts with the same 2500 menu... But it was delicious anyways, and I just loved their special miso sauce. My advice: just try as much as you can ;-)
