Thanks for the input everyone! Is the food at either of the Mexico restaurants in Epcot any better than chefs/BOG? Maybe I should try to find a completely different option.
Having eaten at both restaurants in Mexico, BOG and chefs, I would choose one of the restaurants in Mexico.
I think the food at La Hacienda de San Angel (the restaurant OUTSIDE of the temple) is better, but San Angel Inn is still fairly solid, and eating inside the temple is a very nice, relaxing experience.
