On Sunday, we took the bus to Belém, a district west of Central Lisbon.  We started our morning at Pasteis de Belem, a famous pastry shop in the area.  They are known for their pastal de natas (one of my favorite Portuguese treats - an egg custard tart) and the shop has been around since the 1830's.  Alex and I each got one pastal de nata, a bola de berlim (custard filled donut) and a ham and chess puff pastry.  When in doubt, choose everything that looks good right?!?!
