What’s new this year: two first-time dishes
Monster Gulliver Burg Dish (モンスターガリバーバーグディッシュ)
This is the headline of the 10th fair and the biggest dish the fair has ever served. You get two Gulliver W Cheese Burgs on one plate, plus about three times the rice and about twice the salad of a regular-size dish. One thing to note: extra cheese toppings can’t be added to it.
Gulliver Fondue-Style Cheese Burg Dish (ガリバーフォンデュ風チーズバーグディッシュ)
Added by popular demand, this one smothers a 400g burger in a white, fondue-style cheese sauce inspired by cheese fondue. The sauce portion is about double the usual amount, so every bite is covered in cheese.
The full Gulliver burger lineup
The Gulliver Burg (ガリバーバーグ) is a 400g patty that fills most of the plate. It comes in two basic formats, and the fair builds several variations on top of them.
| Dish | What you get |
|---|---|
| Gulliver Burg Dish (ガリバーバーグディッシュ) | Burger, rice and salad on one plate |
| Gulliver Burg Steak (ガリバーバーグステーキ) | Served on a hot iron plate with side garnishes |
| Gulliver W Cheese Burg Dish (ガリバーWチーズバーグディッシュ) | A Gulliver-size version of the popular Cheese Burg Dish |
| Gulliver Curry Burg Dish (ガリバーカリーバーグディッシュ) | Double the usual curry sauce, with rice and salad |
| Gulliver Potato Salad Packet Dish (ガリバーポテサラパケットディッシュ) | About 3x the usual potato salad and melted cheese, wrapped in patties totaling about 400g |
| Gulliver Fondue-Style Cheese Burg DishNEW | Fondue-style white cheese sauce, about 2x the usual amount |
| Monster Gulliver Burg DishNEW | Two Gulliver W Cheese Burgs, about 3x rice and 2x salad |
Fries, salad, parfait and a giant strawberry milk
The supersizing doesn’t stop at the main plate. These sides and sweets are good candidates for sharing at the table.
- Gulliver Fried Potato (ガリバーフライドポテト): about twice the amount of an L-size Bikkuri Fried Potato.
- Gulliver Spicy Potato (ガリバースパイシーポテト): fries seasoned with an original spice blend for a little kick.
- Gulliver Salad (ガリバーサラダ): nine kinds of vegetables, with shrimp crackers, fried onion and corn among the ingredients, served in a glass about 25cm tall. It has two layers of dressing: the original dressing and a mayonnaise-style one.
- Gulliver Chocolat Parfait (ガリバーショコラパフェ): the regular gâteau chocolat parfait blown up to about 30cm tall, layered with chocolate mousse, salted caramel cream and feuilletine cocoa.
- Gulliver Strawberry Milk (ガリバーイチゴミルク): strawberry milk topped with Hokkaido soft serve, in a glass about 25cm tall.
