We went to the Character Superstar Breakfast at Universal on Nov 7th. Yes, you picked a pre-plated meal, but when we were seated and they took our drink orders, we were told if we wanted anything additional (more eggs, bacon etc) to just ask. We were asked many times during the meal if we needed anything extra so I'm thinking there had been complaints about no seconds. The characters came out in two stages:
1 - Dora, Diego, Spongebob and Squidward
2 - EB and Bit from Hop, Mr Gru and a minion
My only complaint was that we booked and paid for the meal in May and were able to reserve the date, but had to call multiple times to secure an actual time which weren't available until September.
