In-N-Out has more than just delicious burgers! You can stop by and get a warm cup of hot chocolate. It usually costs $1.65 but on rainy days it’s free for children 12 and under! In-N-Out makes its hot cocoa the old-fashioned way – with hot water and chocolate powder, which comes from Ghirardelli chocolate and marshmallows on top. As long as it rained at some point on the day you’re seeking the treat, and the child is present at the store, the deal is valid.
