Something I'd like to add to my original review (please make sure to read that as well) is that in my most recent visit, they had a new guy working the toppings area. After paying for everything (including $1.65 for guacamole) I moved over to him. I asked for the guacamole and he gave me something like half a teaspoon, which he carefully scooped from the container. I had to ask for a little more about 5 times until I just gave up and took my food (at this point I probably had less than a tablespoon).
I've never had problems here like this before, but this was kind of pathetic. I assume it's just a lack of training seeing as he seemed very new, but I still felt it should be addressed.
On another note, in the time since I first ate here and wrote my original review, I began eating meat again after a long time. Having now nearly all of the fillings, I have to say they're fantastic.
Through all of this I have discovered that all of their meatless fillings (smashed jack potato, spinach mushroom, and cornbread) are not vegan as far as I can tell, which is unfortunate considering it would be fairly easy to make a vegan friendly filling to accommodate their many vegan options.
