I found this info for you:
Brick City is an imaginative exhibit featuring numerous
LEGO® statues, as well as play areas for children to build their own LEGO® masterpieces. Whether it's a 10 ft. tall LEGO® C.N. Tower or a 15 ft. long Golden Gate Bridge built entirely out of LEGO® bricks, children and parents alike will be amazed at the intricate detail each statue posseses. In total, there are 800 sq feet of roped off exhibits. And, to ensure safety for all ages, the LEGO® bricks that are available for play are LEGO® Duplo and LEGO® Quatro, bricks that are twice and four times the size of normal LEGO® bricks.
We didn't go into Brick City. We had done the Fun House which is the same owners I think (?), and I was less than impressed. My DD6 loved it, but I think it was pretty basic and small. I would have been much happier if it was $3/person. My DD4 wanted to go into Brick City but she thought it would be like the Lego store at Downtown Disney. I could see from outside that this would be a smaller attraction, and probably not very interactive. There was nothing to do at the front. You had to pay admission immediately. Incidentally, you can get a coupon here:

They also had a special rate if you were doing all those attractions. Something like $20/person. Only worthwhile if you were going to at least 3 of the attractions.
My girls liked Mini-put just up the street. It was a dinosaur theme. A little pricey for mini-put, but it was a full challenging 18-holes and took a while to complete.
