Example Input: I was introduced to the Blair chips by a friend. I mostly ignore potato chips because I really don't like them. However, these I like the most among all the chips in the Blair line. They are savory and can be eaten rapidly. The hot chips are good because they are so hot, I cannot eat them fast. I am so happy I cannot get them at local stores because I would eat them all the time.
Example Output: 5

Example Input: I recently moved and couldn't find a thai restaurant nearby. My favorite meal at my old thai place was massaman curry. I used the recipe on the back on the package when I got it, and it was JUST like what I get at the restaurant! Excellent flavor!
Example Output: 5

Example Input: Grape gummy bears are hard to find in my area. In fact pretty much anyone I talk to about grape gummy bears they think I'm lying. So I bought 10lbs... : ) These bears are a little bit bigger then the other brands and have kind of sour kick, but nothing to strong. I love grape flavored candy/soda and these are pretty good. There is another company that makes grape gummy bears that are a little bit better in my opinion, but these are well worth it for the price. I like to use the gummy bears in home made Popsicles with flavored sports drink. The salt in the sports drink makes for softer popsicles, and the gummy bears are awesome frozen. They are delicious!
