Any concerns about the speed of service should be tossed aside. My family went on a Saturday night and quickly were served the best calamari I ever have eaten, outstanding rolls and melt-in-your-mouth sashimi. Our server was outstanding, and a duck even walked over from the lake to say hello (and bit my finger).
My mom, who is allergic to avocados and let the server know it, was given a roll with (you guessed it) avocado in it. But she loves Hon Machi so much she forgave the chef.
