What will they think........?

I was rummaging through Google in search of entertaining, culturally applicable current events from Japan
and there I found this:

Behold Japan's Monstrous Five-Patty Lotteria Burgers

Lotteria (A national fast food chain in Japan) is celebrating their 40th birthday with a discounted quintuple cheeseburgers and fried shrimp burgers. Wow. 

As the blog suggests, they are sold at discounted price of 500 yen (about $6.35). The 'Super Cheesy" cheeseburger deal is available on the 16th and the 23rd of October and the "Super Fry-day" fried shrimp burger deal is available on Friday October 19th and the 26th. Both of deals from from 2-8pm (14th-18th hours). 

I'm planning on having my students look and decode the advertisement in Japanese (use of authentic material). And synthesize (critically think) why this is a great deal and should be acclaimed. With "health" being such priority in both countries of US and Japan, why this may be "eye-catching".
Will this be accepted in United States? What kind of issues may this rise if Mc Donald's decided to do this in United States. Why do you think it is okay in Japan?
Now, what do you think about the fried shrimp burger? Does it sound appetizing to you? Why will it not be the best choice in US but popular in Japan? 

What do you think they will say? I'm interested to see what kind of answers I will receive tomorrow.
