I stopped by here for breakfast one morning and picked up a Vanilla Napoleon and a Nutella Brioche.
The Napoleon had pretty nice puff pastry in it. It was flaky, crispy, and had a pleasant slightly burnt/roasted flavor to it. The custard was pretty bland though. Its texture was creamy and thick, but it could've been sweeter and more eggy. I couldn't taste any vanilla either.
The Nutella Brioche also wasn't very impressive. There's tons of Nutella stuffed inside which is never a bad thing, but the brioche was kind of hard and pretty dry. It was also missing that strong buttery flavor which makes a good brioche so enjoyable.
Yes, the chocolate fountains are cool, but at the prices they charge for their baked goods, they should taste better.
