I can vouch for the Farmer's Market. It's easy, fast, and tasty!
There's pretty much everything. From Gumbo to Yakisoba. There's pizza, waffles, fruit, and coffee there. It's a nice variation of vendors that is affordable and fast. Really good if you're in a hurry. Also if you can drive or are willing to walk a bit, Ice Cream Rennisance is amazing. Bittersweet Choclate and Coffee are their best flavors. Sorry, otaku foodie rant.
