No Pokemon theme food? How about rare candies, Rage Candy Bars, Lavaridge Cookies, and Casteliacones!?
Zelda can also serve soft drinks as potions and they can come in a glass bottles! Grandma's soup from Windwaker could be a dish too! They can also serve Zelda sweet heart candy grams!
I think a F-Zero sports bar would be pretty cool too.
