We visited Kobe just for one day, largely to experience the beef and we found the restaurant listed in the official guide. We booked a lunchtime spot a day or two before but we were the only two customers in the restaurant which is the only reason the atmosphere was knocked down.
Overall, our experience was amazing though. The beef lived up to expectations and it was expensive but slightly less than our expectations. Potentially the best part of our meal was our chef, Mitsuda. He was extremely informative, personable, and passionate about the food. The experience was exactly what we were looking for and we would recommend.
