I tried the mustard-fried burger at In-N-Out and I loved it. It’s probably my new favorite order. For $11.48, the meal included a side of fries and a medium pink lemonade. For all the risk takers out there, sneaking in your own drink will put you well under the “$10-and-under meal” rule according to my friend Keith.
How to get it? Ask for a mustard-fried Double-Single with a whole grilled onion. It’s tangy, caramelized, and with just one slice of cheese it’s not too crazy.
After all these years, I’m still learning the In-N-Out lingo, but the server behind the counter was really helpful. 10/10
