Let me start off with, I love Cheba Hut. Some of the best sandwiches you can have.
My complaint is recent. The past 7 times I've gone there they have messed up my order. I usually go at night when it's not very busy and get it to go. They have consistently forgotten to add toppings to my sandwiches. In some case they didn't add any. I don't know of it there no system or what.
If you get a sandwich to go make sure to CHECK IT before you leave.
