Algorithm to find best vote based on 5 star

I need some help in finding best logic for vote system which is based on 5 stars.

Logic is like this:

User has to give rating(5 star rating) for 3 questions for one movie or restaurant

For example :

Restaurant name : XYZ

taste : ****** 

price : ***

service : ****

How we can findout which is best restaurant?

case 1:

Based on total stars (in this case 13)

But,

           quest1   quest2  quest3  restaurant
 
user A      4         4       4         AA
user B      5         5       5         BB
user c      1         1       1         AA

In this case AA and BB has same vote?

case 2 :

Average stars (sum of users rating / number of user rated)

           quest1   quest2  quest3  restaurant
 
user A      5         5       5         AA
user B      5         5       5         BB
user c      1         1       1         AA

In this case, AA = 18/2 BB = 15/1 ?

Any suggestions to get better logic?

You will always have ties, so there is no one way to find the best restaurant. For example, 2 restaurants that have all 5 stars.

You could have other data points which support the choice of the restaurant, such as which review was first. The thinking behind this is: the longer a record has been in the system, the more chances it has to have been tested.

You could also have a way to find out which restaurants are the closest to the user and break the tie based on proximity: a 5 star restaurant 1 block away is better than a 5 star restaurant 10 blocks away.

My 2 cents. :)
