List column is a multivalue Lookup Column - How to report individual totals

Relatively new to PowerBi - and have a query on how to achive something,

My data source is a SP List - that has multiple columns two of which are Multivalue Lookup columns.

I am trying to create a report that allows me to show amount of times an individual value exists.

So as an example if the source list columns were.

Date                         Restaurant Name    Food eaten(lookup column)

01/01/2019             Mcds                       Burger, Chips, Drink, salad

01/01/2019             Freds Diner             Burger, Drink

02/01/2019             My House               Salad, Drink

03/01/2019             Mcds                       Burger, Chips

How could I create a report that on it I can show amount of times Burger was eaten (i.e 3) and obvioulsy be able to equally say how many times Burger was eaten at Mcds (2).
