China - The kiosk in front of China has this really good curry chicken pocket thing. It's in puff pastry & I don't know how authenic it is - but I love it. I crave it. I've had the BBQ buns & didn't find them as good. This stand also has eggrolls that are a little more mainstream.
Japan - The Mitsukoshi Dept. store has all kinds of interesting snacks in the room in the back. If you don't like sushi, there might be something you'd be willing to give a try for a snack back there. I'm partial to shrimp chips myself. (Not as weird as they sound, honest.) There's also a sake bar in the same room. Additionally, the quick service resturant has a really tasty curry dish. No sushi involved.
Morroco - My husband & I share a lamb platter in Morocco often. We really like it. (lamb gyro, cous cous, tabouleh, hummus & bread) I've also had the vegetarian platter & really enjoyed it. (cous cous, hummus, tabouleh, lentil salad, marinated olives, falafel, & bread). They have a "slider" platter that intrigues me, but haven't convinced the husband to give this a whirl yet. Sharing a entree here is a great snack, if not a meal. (I tend to eat smaller meals, so this works for me, but it might be a snack for a lot of folks.)
I will also say that I've had 3 or 4 of the different appetizers in the Cava de Tequilla & they were all great.
Have a good time!
