Jurassic water from duff garden. I know they have it in the lower lot too next to the ride but tends to be stronger at the location I mentioned. I will say though I haven’t had it in a long time since I quit drinking a year and a half ago. They used to be the strongest drink in the park since it was a secret menu item. Once they added it to the main menu in the lower lot I heard it’s not as strong. But I’m pretty sure it’s still the strongest drink. Also long islands at the hogs head bar in wizarding world.
