Cupcake Mission, which "seeks to change the world one cupcake at a time," is coming to New York tomorrow, Tuesday, June 23rd. Cupcake Cafe, specifically. 18 West 18th Street (off 5th Avenue), NYC.
Here's the scoop from Meg Weidner's Team Fox page:
It's time to stop calorie counting and enjoy cupcakes at The Cupcake Cafe to raise money for a great cause: MJFF! Cupcake Mission is literally a mission to change the world one cupcake at a time and this mission is taking Manhattan to help raise money to put the MJF Foundation out of business! Dedicated in loving memory to Meg's grandfather, Opa, who was always an incurable optimist...may you always feel like the sun is coming out!!!
via Team Fox blog. Those are all the details that are given, so I'm assuming that cupcakes bought anytime tomorrow are included, but double check at the cafe if you go.
