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: On Sunday night, it was around 8 when I decided that I didn't feel like cooking dinner, so we hopped in the car and decided to head over to Red Bowl for a quick bite. Despite the fact that the restaurant was not busy, our service was rather sub-par. Also, I was not happy when I ordered my dinner with brown rice (as I always do) and was told that there is now a $1 up-charge for brown rice. WTH?

Incidentally, I have some good friends who used to frequent this place who are now boycotting it because Red Bowl has started cheaping-out on everything including their sushi specials. They are definitely losing some of their loyal customers with some of the changes they have been making.

Before this, Red Bowl was never my favorite spot, but it was cheap & quick. The quality was always hit-or-miss, and on this visit, the food was so-so. My flower chicken was ok (bland but not gross), the brown rice was meh, and the chicken egg roll was downright gross (it tasted like a frozen egg-roll that was not very fresh or warm). Based on the food & service on this visit, next time I am looking for a quick bite of Asian food close by, I will head over to Jo-Jo at Stone Crest instead of this place.
