I've decidedly tried to steer clear of the EpiCentre however, I didn't want to leave Uptown to see Inception so it seemed like a necessary evil. Probably one that I will endure again because there are assigned seats with generous food and cup holders between the large comfy seats and the theater was very clean.
The matinee is more benign in regards to the pomp. I didn't see bouncers or attendants in the bathroom. As others mentioned there is a full bar and hot food. The only down side about allowing people to bring food in is the smell.
The parking is validated for up to 3 hours by the parking lot attendant by showing your ticket stub. Good to know when walking conditions aren't good. Tickets can be purchased on level 2 and then you take the escalator up to the theater and bar areas.
