Teacher: You are given a review about a place. You need to provide a rating from "1 star" to "5 stars" for this place.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Although I did enjoy the food here, I was completely unimpressed (and slightly annoyed) by the overpriced margaritas. I ordered a platinum which contained "fresh" juice. It tasted like it had sprite in it, so I thought surely she gave me the wrong one. It turns out that "fresh juice" is really margarita mix on tap from the same gun as the sprite. I asked for something fresh to replace the horrible margarita and received a rocks glass with just muddled lime and a salted rim. I'm not sure it contained any tequila. Horrible! It's not that hard to make a fresh margarita!
Solution: 2 stars
Reason: The writer has been annoyed in this place and has enjoyed the food. So, "2 stars" sounds reasonable for it.

Now, solve this instance: A wonderful green space in the centre of this big Scottish city. We had a wonderful sunny afternoon and took a stroll through these gardens. The floral clock is really nice and has a display every half hour (I think!), it makes for a really nice walk through the city and the green of the grass is perfect. I hear it used to be the dumping ground for sewerage in the 14th - 18th century! (No wonder the grass is so green!) It's a beautiful spot to check out in Edinburgh, a bit of a hidden gem!
