We all know Twilight loves burgers. Really loves them.

So, where would be a good place to take Twilight for a burger?

I hear Whathayburger has a good variety, and some all-time favorites she'd likely enjoy.

In N Out; less selection, less rick of Menu Paralysis.

Better off making her one yourself. Learn to cook hayburgers and hayfries, pick good ingredients and take a class at a local course. You'll produce a better burger.

Earth or Equestria?

If you teleport her to the G5 universe, take her to Zephyr Heights and to McWings.

I hear all the pegasi there sayin' 'I'm lovin' it' coupled with a giant golden W.

Homemade with select herbs and spices mixed into the fake meat patty. Sauteed peppers and onions, barbecue sauce, guacamole, spinach, mango, grilled pineapple rings, goat cheese, and mushrooms. Yeah, that sounds like a burger Twilight would like.

The Hayburger, it was outright mentioned in the show. And Twilight said that she liked the food there.

As for the human in the equation though, they would need to see if there were any oatburgers available.
