I’m one of those people that always worries I’m missing out on a good meal by choosing a crappier location. While the Expo maps themselves have a listing of the food joints there, it’s hard to tell details like whether Yun’s Fusion Cuisine is fancy or if Yonho is not (assuming you’d never heard those names before). So I’ll probably find this Expo guide from CNReviews pretty handy for the next time I head into the grounds. They’ve got mini-reviews, price ranges and other descriptors of restaurants on both the Puxi and Pudong sides. Yum!
