I've come here several times for lunch and it's never busy. I like it because it's clean, has plenty of seats, and the employees are nice. I rarely dine inside of a McDonald's, but every once in a while, I will get a Big Mac Attack and come inside to take care of it.

I've also tried their new Angus Bacon Burger. It's not bad. The Bacon is the super thin kind, which I don't really care for, but the Beef is better than their regular Burgers.

Overall, this location is OK for a Mickey D's.
