I've been to Shiru-Bay a number of times and I'm in love with the food here. I understand what happens at this restaurant and the challenges so I avoid the busy times and go with the flow of it... however, if you hit it right, and I do now almost with precision when I go there, it's an amazing experience!!!
Rule #1: Go early -- no need for reservations if you arrive when they open at 5:30. Sit at the counter if it's offered. It's just as comfortable, if not more so, if there's four or less people.
Rule #2: Plan the dishes you'll eat in what order with the waiter. Order only a one, two or three dishes at a time -- and then enjoy. Each mouthful is a wonderful experience. Don't get ahead of yourself. Only when you're finished and have savoured these dishes, then order more food. If you order 6 dishes for 4 people right away, they come too quickly and the hot dishes get cold while you're picking at all of it at the same time...
Rule #3: Find out who the head chef is, and make contact, eye contact with him. Send him a thank you via a server when you are extremely happy with a mouthful or a dish. This is part of the experience. Also, if you've had a particularly good time that evening, tell the server to tell him when you're leaving that it was particularly good, and to let the chef know -- and follow up on this message if it's busy.
Rule #4: Ask the waiter for recommendations. Be calm and truly get their advice, their personal taste. There are secrets in the menu that don't meet the eye on first glance. The dumplings wrapped around asparagus, the rice hot pot slow cooked with pork... these don't jump out at you, but they are divine!
Rule #5: The servers are young and impressionable, so you need to guide them to what you want and need, they don't know enough to anticipate like you would find in a more sophisticated place. But, this is okay. Just tell them exactly what you want and when, and you will get it.
Enjoy! I do!
