A typical legal rationale for protecting the consumer is based on the notion of policing market failures and inefficiencies, such as inequalities of bargaining power between a consumer and a business.
It sounds kind of expensive when you first check out, but it's actually pretty cheap if you consider it. Take something standard like a Philly roll (nori, salmon, cream cheese, cucumber, avocado). At Maki it will cost you $6, but the roll is pretty fat and you get 10 pieces. Most sushi bars charge around $5 and give you 6-8 pieces.
This makes a fantastic meat for Philly steak sandwiches. You can even use lower grade roasts and have this turn out. It also makes its own au jus if you like to dip as I do. To serve, sautee a sliced onion and sliced green pepper in a skillet.
