Restaurant Review Ratings - Explained

Have you noticed that the overall rating of a restaurant isn't always the "average" of all of the individual categories? ... Well here's why:

We [the organisers] feel that having a slightly stale poppadom or being in a restaurant with bad taste in music or decor shouldn't have the same influence on a restaurant review as a bad main course. So, each category has a weighting factor applied to it (as shown in the table below). However, if you have a really bad starter (for example), determined by a bad rating threshold, then this should have an increased influence on the overall review.

So, our cunning systems engineer Brian Donaghy came up with a cunning and [not so] devious plan to better reflect ratings:

  1. Normal weighting factor applies to all rating categories which is unbiased, e.g. a 3.5 in each box gives a 3.5 total ... unless ...
  2. The category rating falls below a set threshold in which case the weighting factor for that category becomes 50. This shows a general un-satisfied feeling for the meal as a whole and should be taken into account.
category normal weighting bad rating threshold
pre-starters 4 0.5
starters 7 1.5
mains 10 2
tapas 10 2
sides 7 1.5
service 6 1.5
atmosphere 3 0.5
value for money 10 2

Obviously, if no category has been rated (for example if you didn't have any sides), then its weighting factor simply isn't included in the calculation.
