This is the 1st time I have EVER went to a restaurant where I had to go through a security check. They will search your bags. You will have to go through a metal detector. I was last here 10 ish years ago and this was never a problem. Crime in the area has risen significantly since then and there were a lot of homeless hanging around the area when we were there.
When you arrive there will be 2 lines, 1 specifically if you have chosen a premium table and 1 for regular. There can be lines to wait to check in. Wife signed us up for a premium table. Once your table is ready and you get through security (smh), someone will escort you to your table and explain a few things to you. You will have 1 hr 15 min to reside at your table and they ask you to stay there until after you finish eating. Food is priced based on the category you choose (premium or regular). For premium it is $45 / person (kids too). Premium tables reside next to the waterfall. Total bill for 2 adults and 2 kids was $230 (most I've ever paid for a meh meal, maybe for any family meal). There are a lot more gluten-free options if you need that (their website is outdated and doesn't reflect that). After finished eating you can get up and go see the attractions.
Kids did enjoy the cliff divers, the arcade area ($5 for the shooting gallery) is expensive and outdated. The whole place is very crowded.
