We waited 20 minutes for the Japanese Fluffy Pancake last night. We're still debating whether it was worth the wait. (By the way, you can add upwards of 10 minutes waiting in line just to order.) This dessert is certainly fluffy and eggy, and it's this texture that really stands out. We tried the strawberry version of this, too, and don't recommend one versus the other.
What is worth the wait (about five minutes) is their Royal Ceylon Milk Tea with Tiramisu Puff Foam. My goodness, that smooth, rich, coffee-flavored foam might be reason alone to come back.
