When I called a couple of days ago the concierge at the dolphin said pikabu's (the new name) is scheduled to open after the 1st of April. He said sometime within the first two weeks of April.
Luvdmouse, thanks for the reply. We'll be arriving on Apr. 16, so it sounds like we have a good chance of being able to check it out. We enjoyed a great breakfast at Tubbi's last year, and thought we might try it again. I wonder if Pikabu's will have the same food and mode of service, or if it will be all different. Guess we'll have to go see!
Tubbi's is a buffet/cafeteria style eatery located at the Dolphin hotel. Nothing fancy, but I've had good food there every time I've eaten there. Plus they give a 10% discount to DVC members, which is nice.
