How sweet is this? The Sweetflow Mobile, that rolling froyo operation from Sweetgreen, will be giving away “FREE small cups of sweetflow with toppings this Saturday,” according to its Facebook page.

And not just once, but twice. The truck will be parked from noon to 2 p.m. at 25th Street and Pennsylvania Avenue NW and from 3 to 5 p.m. at 5th and K sts. NW. Freebies will be available at both locations on Saturday.

“There will be more freebies that won’t melt in your cup,” the Sweetflow folk promise, “so bring your friends and your dancing shoes — let’s make this Saturday an epic one!”
