I can make some quick translations, since it's a very short & easy to translate special.

Yuya: -It's noon, huh... I'm fed up of preserved foods, guess it won't hurt to have lunch outside once in a while...
Yuya: -I wonder what I should eat... (something about eating on "Oomori Ramen")

Yuri: -That's outrageous!

Yuto: -That's right, only Yuya can eat whatever he likes outside...
Yugo: -Let us pick something we like to eat too!
Yuya: -What are you guys saying? The one who'll be eating is me, am I right?

Yugo: -If you switch places with us, then we too will be able to get the feeling of tasting real food!
Yuya: -But then it'll be as if I didn't actually eat, won't it!

Yuto: -If we have to pick something for lunch, it really should be "Curry", after all...
Yugo: -Nope, it clearly should be some "Tongatsu" soaked in oil!
Yuri: -Lately, it seems like Yuya has been lacking physical training... For the sake of our beauty and health, it would be prudent to skip lunch... [Kank's note: That's not how things work, Yuri-tan]

Yugo: -Skipping lunch is completely out of question! We're having Tongatsu!
Yuto: -Currey!
Yuri: -We are going on a diet!
Yuya: -Listen when someone's talking, geez!

Yugo: -Yuya picked "Ramen", right...?
Yuya: -Y- Yeah...

Yugo: -Then, let's settle down who gets to choose!
Yuto: -Very well! But unfortunately, only Yuya has a Duel Disk...
Yuri: -In that case, let's decide it with Janken.

Yuto: -Let's do this!
Yugo: -Let's go!
Yuri: -Here I come!
Yuya: -Ack, geez! Janken...

Yuzu: -It's decided, then! We're having noodles!
The Yus: -Whaaaat?!
