Oasis or Mirage is currently in the works of implementing a new rating system to each review. While not all of the reviews are updated, you will notice on newer posts that each restaurant is rated on a scale of 1 to 10 in three categories: Ambiance, Food and Service. I take the three scores and find the average which is the Overall score. If that score is a 7 or above the restaurant is deemed an Oasis and if it is lower than a 7, it is a Mirage. If the numbers do not add up to a whole number, I round that number depending on the decimal to the nearest whole number (for example, if the score is 6.4 it would be a 6 Overall but if the score was a 6.5 the Overall score would be a 7). Eventually all of the reviews will be updated using this system but for now, please enjoy reading the reviews on the posts that haven’t been updated.
