Well at City Walk (the area that connects the 2 parks) there are lots of great restaurants.
We love Margaritaville ~ great atmosphere, music and food, the kids menu is good and reasonable too.
Also we like the Hard Rock Cafe.. fajitas are really good here
There are so many neat places to try I have heard good things about Pastamore, NBA Cafe & NASCAR Cafe, Bob Marley, Pat O"briens, Latin Quarter, Emerils & Motown Cafe...
I know there is a Deli and a nice Italian restaurant in your Hotel but I am not sure how late they are open. Room Service might be an option as it is so late.
Our trips are very similar... I do hard rock and then head for the Beach Club concierge and I see you are at YC Concierge... it's a small world
(after all) lol
My whole Disney trip is completely planned ~ I have absolutely nothing planned for Universal other than going to sea world one day
It is very relaxing there and with FOTL access you can accomplish so much in a few hours - it's amazing.
