I did something rather stupid: bought groupons for two huge sushi platters at Sea to You planning to serve it to a party I am having in the end of the month. But when I called to find out when I need to place my order (day in advance), I noticed that they are closed on Sunday. And my party is on Sunday!!!!! Not sure what to do now. I really counted on serving this sushi. I cannot put them in the fridge, can I?
