This is not one of the nicest theaters in town. The location is so weird, it's in this mostly abandoned shopping center tucked away from the hustle and bustle of town. While the theaters technically have stadium seating, the seats are old school and very uncomfortable. The screen size is good and the projection and sound systems are good.
I see movies here mostly because they like to play some obscure, foreign and indie titles that you can't see anywhere else in town, and they always have the special RiffTrax / Fathom Events screenings (one of the only theaters in town that consistently has these shows; ticket prices for the special events run a bit more at $12.50 per ticket). The Colonnade also has movies around for a lot longer than other theaters (so if you've been wanting to catch a film that was released 2 months ago, there's a good chance it's still playing here). You can avoid the skeevy-ness of the $1 theater by going here instead.
There's a huge parking lot and since the shopping center is always empty, parking is never an issue. The lot is pretty dark so try to park close if you are a woman going alone. In fact, the parking lot is so dark that I wouldn't want to go see a movie here alone at night (management, are you listening?). The theater is set back from the main lot so there's a bit of a walk to get from your car to the lobby (not fun if it's a blustery or rainy day).
The snack bar is just okay. I have had old and stale popcorn 3 out of the last 5 times I purchased snacks here so I've stopped wasting my money.
A little patience goes a long way here. This location likes to hire special needs employees (which I wholeheartedly applaud), but be aware that sometimes their people skills aren't the greatest and sometimes they aren't as speedy as you'd like them to be. No matter, the positives of giving people a job far outweigh the negatives!
