Park was packed yesterday and today. I'll second
@horsesboy 's observation that food lines have been unacceptably slow. But I will say this: both Grain & Grill and Outpost (those were the only two restaurants I visited) had tons of staff inside, like a dozen or more employees per restaurant. It just looked like most of them had no idea what they were doing. In Outpost's case, they kept running out of food and having to stop the line completely while they finished cooking the next batch.
Given that the staffing numbers themselves didn't seem to be the issue in those two locations, I expect the service to improve as the employees get into their groove and get more practice. That doesn't
excuse the poor service, but I think it's important not to lose sight of the fact that for many of the park's staff, this is only their first or second day on the job.
