Sadly Donut King is out of business. I hope to see them pop up here in Belen again soon. Used to be the best (and only) place in town for fresh donuts.
Heard good things about this place, BUT THEY ARE CLOSED INDEFINITELY FOR REPAIRS. (December 22, 2016)
This place is one of the historic social hub of Belen,where you have coffee,donuts,muffins,etc and chat with the locals. I and my Dad go everyday in the morning.
