I once ate grocery store sushi, but I'm not sure if I was open-minded enough at the time to appreciate it. I should try it again when I'm feeling brave enough.Grocery store sushi is mainly horrible. Don't bother, go to a restaraunt. If you don't like it, at least then you can order teriyaki or ramen instead.
Note: advice on grocery store sushi can be ignored if the grocery store happens to be in San Francisco. OH MY GOD WHY DID EVERYTHING TASTE SO GOOD THERE
