This place is a RIP OFF. These people are stingy beyond belief. I asked for spinach on my sandwich and the guy behind the counter put 4 leafs on it. Asked for more and he said it would be extra - insane! I asked for cucumbers & he put 2 on there. The woman behind the counter had a nasty attitude when I asked if I could have more than 2 tiny triangles of cheese on my sandwich, and asked me (no exaggeration) 4 times if I wanted cookies or chips, which I didn't.
$14 for a garbage sandwich. Looking at the other reviews, I should've known better. Absolutely terrible.

I don't like posting negative reviews but this place has EARNED it! Zero stars if I could. I understand that businesses have "off days" but this place seems to be off all the time! Lettuce looked old and they are extremely stingy when it comes to any and all vegetables with the exception of the old lettuce. They also charge $0.10 a bag but they don't mention this and still give you a bag but I believe they charge $0.10 by default. Seriously a small paper sandwich bag for $0.10.
Avoid this place at all costs.

Just came in for a soda and there were fruit flies everywhere. Now I’m worried if the soda machines are clean.
