If your Otters are Shake Shack fans, mark the calendar! Two weeks from today - on Wednesday, April 20 - the Shake Shack in Navy Yard is offering a giveback day to benefit the Van Ness Elementary PTO. This means if you get Shake Shack that day, they’ll give 25% of sales back to the Otters. There’s no way to go wrong ordering good burgers/fries/etc. for a good cause!
