Parallel planes with location

We have explored models that included the quality of both food and service, as well as location, but we haven't put these variables all into the same model. Let's now build a parallel planes model that incorporates all three variables.

Examine the coefficients closely. Do they make sense based on what you understand about these data so far? How did the coefficients change from the previous models that you fit?
