I am not vegan so 3 stars is a very high rating from a meat eater. The good here is good enough that I would eat it again.
If you aren't vegan then I would stick with the curry and spicy items. Although the cheese-steak is very close it isn't as satisfying as one with steak.
I don't know how much healthier the food is than the traditional alternatives, but the prices are very reasonable.
Where this place shines has to be the quality of service and the friendly proprietor. I went in late on Sunday and he was all by himself hustling to get our order ready. He had a very upbeat attitude and asked all the right questions to make sure we had what we needed for our order.
There is a little grocery section with vegan items on the wall. I didn't get any of these but they are there.
Definitions of things used in vegan cooking were proudly displayed - it seemed this place was working hard to educate consumers on vegan foods. As a non-vegan I really appreciated this.
The biggest downside is that this place is in the cut. You can't see it from the road and if you don't already know where it is the GPS doesn't help you. You need to pretend you are going to Hibachi express and then slowly go deeper into the parking lot. You will then see Zizis with signage painted on the glass door. I strongly suggest you use the street view of Google maps along with the normal map to get the exact idea of how to find this place. We zipped right past it and ended up turning around at Walmart.
