"I want to go to the restaurant where they say trebuchet"

A bit of background:
Our favorite Japanese restaurant is Miyake's in Palo Alto and Cupertino. It is great for lunch, but gets a bit crowded, loud and noisy at dinner time. Anyway when you are seated, the waiter who seats you yells something that ends with "shea," ALL the other waiters and sushi makers yell back to him again ending with shea. Over the years we have gone there, we have developed our own inside joke that they are yelling Trebuchet, because that is really what it sounds like. I am sure they are saying something is Japanese to welcome us or something, but it literally sounds like trebuchet.

I don't know where Chanler picked this up, because we don't make that joke much anymore (because it is old to us), But we were driving in Menlo Park one day talking about getting some food when out of the back some the phrase above. I was floored and a bit embarrassed. I mean if my kid knows a restaurant well enough to want to go there . . . I must be eating there too much.
