If you've been to 1 MAC location, you've pretty much seen them all.
Just your typical MAC set-up in the Dilliard's at the Galleria at Sunset. It is small, located right near the store entrance/exit into the mall and gets really crowded.
If you plan on having full make-up done for an event, I would suggest making an appointment. It gets really busy, but the staff is awesome, friendly and very helpful.
I am usually just in and out picking up what I need and don't do much browsing....
