Most of these replies don't even make sense. EVERBODY at your table got sick?
sounds more likely that one of your little kids had the flu and gave it to the rest of you. The food was cooked from a book? WTF?

They are called cookbooks. They are not uncommon. As far as "overpriced food", in my experience Sushi is not the best arena to go bargain shopping. The "reviews"on this site seem less helpful everday.
