Just visited this morning and Adam took my order, he was so polite and respectful. The food was delicious and I will return to this location again… Thank you Adam for doing a great job, we need more workers like you.

Went through the drive thru this morning and first I didn’t get the large soda that I asked for and was handed a medium but that’s not a big deal. What is a big deal however is the ridiculous amount of mustard they drenched our burgers in. I don’t know one person that drenches things in mustard like that. I had to wipe half of it off with a napkin just to eat. Do better.

Great food, but more important, outstanding service. The employees there were friendly and very hospitable. This was the best quality service I have ever experienced in a restaurant, and I have been in many restaurants, from fast food to high end dining.
