Mmmmmm so many good ones! I am partial to Mexican and LOVE the Cantina de San Angel in Mexico. DH and I split the Plato Combinacion and a churro and margarita. Mmmmm.
Now if you were to ask DH, he would say his favorite is in the UK. He loves the fish and chips with some malt vinegar and a black and tan from the pub.
Probably the only CS I wouldn't have is the one in the America pavillion. The only thing I'll get there is funnel cake because it's just too good to resist. I can get burgers, fries and turkey anywhere...so I like to try the other countries first.
