I was working in Phoenix for two weeks and this was my absolutely favorite place! My coworkers and I loved it so much that we came back 3 times (would've been 4, but Zupas is closed on Sundays).
My favorite was the thai coconut tofu bowl! You get so much food for less than $10. Only bummer is that it's not included in the try two deal. I liked the try two deal when I tried it another day. It provides a nice light meal and lets you sample different items on the menu.
And the "cherry" on top is the chocolate covered strawberry that comes with every meal. Note that sometimes your friend will get a giant strawberry and you'll get a tiny ass one.... but the amusement this causes is more hilarious than anything else. There are also other desserts and I was definitely a fan of the rocky road brownie.
