The limit of pies does not exist — there are pizza pies, mile high lemon meringue pies, coconut cream pies and so many more. Take your love of the versatile and delicious round treats and put it to good use at Flour Bakery+Cafe’s (Seaport location, 19 Drydock Ave) Pieapalooza on Sunday, May 19th. It’s all-you-can-eat (and the choices will be more than you can imagine) so make sure you come hungry. Tickets are $35 with proceeds going towards BUILD Boston, a local organization that uses entrepreneurship to empower kids from under-served areas and help them create skill-sets for success in high school, college and beyond. Pie eating starts here.
