We ate at both last month.
Express
Breakfast was deserted at Express. They missed an entire entree on our order, so we got it free; service was great otherwise. We walked by around 7pm and there was a line 10-20 deep outside. There's very limited seating.
Cafe
Had supper here & made a reservation just in case. Interesting, but not fantastic menu. Got a pizza. Again - good (better than Disney), but not wow. It was also pretty loud and servers were numerous & zipping by. Not a relaxing environment. If I ate here again, I'd pay a bit more to dine in the nicer area upstairs.
Enjoy!
