I've been to a few Schlotzky's around the valley and this one is actually surprisingly one of the nicer ones. It's clean with plenty of space for even the largest working group lunch. Service comes quick, and they have this southwestern sandwich that is great!
If you're one of the many people who work for a large company on the Dunlap corporate freeway, this is not a bad place to grab a bite before the second half of your work day.
One quick tip - it's kind of tough to find, but it's a stone's throw north of Dunlap on the frontage rd. You have to go back and around a building to find it though.
