This year they have the Ebi burger with Thousand island sauce or Sesame sauce.
For the fries they have Seaweed seasoning or Wasabi powder seasoning.
Ebi burger with sesame sauce:
I tried this one first because the taste is not as strong as thousand island sauce.
The sauce was slightly sweet but matched the prawn patty and the colour of the sauce was beige.
Ebi burger with thousand island:
But when it is shaken properly the wasabi and the sweetness really enhances the fries.
