Sonic vs Whataburger Nutrition Compared

Change either order and watch the difference move. Compared as served, not per 100 g — portions differ between chains, and that difference is part of the answer.

Start from

What’s in this order?

One beef patty with one slice of cheese on the chain's standard bun. Burger King, Whataburger and Sonic publish their burgers built, so the Whopper's mayo, the Whataburger's mustard and Sonic's ketchup and mayo are in these figures. Five Guys publishes parts only and treats every topping as a free extra, so it is shown bare — which is why its sodium is a third of the others'. Single patty everywhere.
