Well, I only order their Chocolate Overload Cake, everytime I come here, & it’s the best dessert for me. It’s cheap & truly delicious. You should try it!

Quick service with the app order. Just the other people entering in the drive-thru before me that slowed down the service just a bit.

Came through for one reason and one reason only because I heard my homie jack done put a cool coke machine in and wanted us all to sniff it out and try it out and let him know what we thought and to be honest it had all the flavors in the world plus they had free napkins good looking out Jack, great spot and best dining I received in a long time.

First time I went here the drive thru was closed and there was no cone in the drive thru. There was still someone on the speaker to tell me that they were closed which is confusing. Second time their fryer was broken so I could only order grilled foods. Why even be open at that point? The Jack in the Box near Foothill and Rochester is so much better

Very bad service. They had one lady cleaning and taking orders so I had to wait for her to be done mopping while another lady stood their politely and said that my order will be taken soon.

Used to be a good off the freeway stop. Younger kids are working there and not sure if that’s why the quality and service went down. I had to ask for my card back and was given the wrong order (didn’t notice until back on the freeway) and was missing food.

Nicholas is the coolest employee. He actually makes you feel welcome and his energy is contagious. Never expected a fast food experience to make my day, but here I am
