I was happy to find Grad School while visiting Springfield. It was nice to go somewhere where I could get some vegan food that was not Subway, Taco Bell, etc. As mentioned in other reviews, there are several menu items including Rasta Pasta, Baja Burritos, and Tacos where you can pick your protein, and a falafel patty is an option.
The good news is that gives you several dishes to choose from. Unfortunately, my husband and I did not find the food to be that great (we had the pasta and the burrito). The falafel just didn't go very well with the rest of the food, and it wasn't even very good falafel. That being said, the portions are huge, it's reasonably priced, and the atmosphere is fun.
I would consider going back if I was in Springfield, but would definitely be up for trying somewhere else if they had veg options.
Cons: So-so food
