Do I need origin premier to play Dine Out?

In the store find the pack and then click the buy button.

Just to clarify for anyone else with this issue: the guy with limited communication issues above is saying you should use the IN-GAME store

Whether you purchase from the Origin Client or Origin.com doesn't matter as long as you are signed in to your account.

Hello, 

The game wants you to buy premier so that they get extra money. But if you click on get the game then scroll down, you can see that there is a button where you can just buy it without getting premier.

So my answer to your question would be no

I hope I helped!
