I would probably give it about 2.5 stars, but I'm giving them the benefit of the doubt.
I've been here numerous times over the years, and the entire experience - from food quality to customer service - is hit and miss. Some times I've gone here to find an empty lobby, perky employee, and quick service - while other occasions I've experienced slow service, sloppy food, or iffy employee attitudes.
The neighborhood along Boulder Highway can be sketchy in some patches, and that is reflected by some of the patrons I've seen here.
It's the closest Burger King to me, so it's where I go if I have a hankering for one of their chicken sandwiches, or if my kids want some cheap chicken nuggets.
If your expectations aren't too high, you'll probably find it to be an acceptable location.
