I'd wager they'll try things, because for something like Hot Dog Hall of Fame, they could do something simple in the terms of grab-n-go.
Considering Universal apparently has reopening dates for the Hotels in mind too, I'd say nothing is off the table for at-least Citywalk. At the very least; this should hopefully allow Universal to gauge how to handle things going forward for the sake of COVID-19, in measures that can be taken.
