Yum, your dinner looks delicious! I usually eat about 10-12 pieces when we go to our favorite sushi place. A couple of nights a week, they have a sushi "buffet." It's not really a buffet; they bring it around to you, but it's all you can eat. You also get a spicy tuna appetizer, cucumber salad, miso soup, and a "poupou" platter. So I really pig out and eat my share of the other stuff, plus almost a dozen pieces of sushi. I love that stuff! My hubby can eat around 24 pieces. One time my son asked the guy that was bringing the tray around what was the most sushi he ever ate at one time and the guy said 50 pieces!
My son wanted to challenge him, but I think my son *only* got up to around 36 pieces and had to stop.
