Definitely get the lanyards. They are $10 but worth it because you have to swipe your express pass for every ride and to go from one park to the other on the Hogwarts express. It was so much easier to have them around our necks then to pull them out of pockets or bags and risk losing them.
We enjoyed our meal at Leaky Cauldron. City Walk has mostly chain restaurants and fast food.
I agree that Mummy is the best ride, with the two HP rides as a close second. Oh and the Jimmy Fallon ride was great too. But these are all VR/3D type rides and I do find they make me much more motion sensitive than old school roller coasters.
Oh, and you need to stash your stuff in a locker at just about every single ride. It's a pain honestly. At WDW you can have a bag/backpack on just about every ride including coasters but not at Universal. And we quickly discovered that every locker set up is different. Some cost money. Some use a pin code. Some use a finger print. And my BIL learned the hard way that they empty the lockers after about 4hrs even though there aren't signs informing you of such. He had his belongings moved up to front gate lost and found from the Hogwarts ride. So, if you can go to the park with no bags you'll have the easiest time. Otherwise at each ride you have to add in time to locker your stuff and retrieve your stuff immediately after.
