Do you have to buy a ticket to Universal Studios to be able to get to the restaurant?

No ...there is free access!!

No, it is outside the park. However, you'll still have to pay $20 to park if you drive.

Its free parking after 6.. We would love to have u come and eat and have a good nite..

No, all for the restaurants and stores are open to the public without a ticket, but parking can be an issue.

I believe they do have half price parking after 6pm. But no ticket to park required as it is outside the park.
