Burger King is offering 3 avocado enhanced burgers: the Fresh Avocado Burger, the Fresh Avocado Whopper Jr. and the Fresh Avocado Whopper Premium. This photo makes them all look pretty good, but the real burger might look somewhat different after the avocado shrinks down. A recent McDonald's avocado burger looked completely different from the advertisement.
The Fresh Avocado Whopper premium claims 50 percent more avocado (compared to what I'm not sure), but it does look like almost a whole sliced avocado. That might make it worth the 550 yen price. バーガーキング アボカド
