The only other Maoz I've been to is in New York City, and while the two (and likely all other chain locations) were virtually identical, I did find a couple differences.
I had the regular falafel sandwich, which was $4, but since I only had a credit card, I had to add hummus to bring the total up to $5. I got my usual toppings, including roasted broccoli, dilly cucumbers, hot sauce, and tomato/onion mix. Yum.
In addition to the usual tahini sauce, this location had a mango curry sauce on the salad bar, which was absolutely delicious. It was pretty strong and I probably wouldn't want it on the entire dish, but just a little on half of my falafel was great.
I have to say that my favorite feature of this restaurant was the public sink they had for people to wash their hands. I hate eating without washing my hands first (especially messy finger foods like falafel), so I was really happy to see the sink. I was also glad they had a bathroom for customers, which New York Maoz also lacks. The space was huge (another difference from the NY locations), and so it was nice to not have to fight for a seat and be able to relax.
