Example Input: We bought these chips at a little sandwich shop in Sonoma while we were on vacation. I wasn't sure what to expect by the package, and at first bite I didn't know what to think...and then all of the flavors hit! Yum! They are a bit spicy, but nothing overpowering. Just lots of crunchy, sweet, spicy goodness. They aren't sold everywhere though, I'm still trying to find them somewhere close to where I live.
Example Output: 5

Example Input: I was amazed at how good this is for canned fruit (which I normally won't touch). In particular I adore papayas and mangos. The fruit juice instead of syrup is also very nice. The easy pull-top on the can makes this a great item to stash in my desk drawer at work, so that I can have a fruit snack easily even if I was too busy or forgot to bring lunch. So far I haven't gotten a can that had any problems. The watermelon isn't crunchy - of course not! - but it's good, and certainly not "slimy".
Example Output: 5

Example Input: You can't beat the price and taste of this coffee. It will always be my first choice to buy. My husband brought it home one day because he liked the price and thought the the can looked neat. Little did we know it would become our new favorite.
