I'm getting hungry just thinking about this place.
As mentioned, they have pretty good natas (Portuguese egg tarts) but they also have these freakin' amazing cannoli (the tube shaped pastries filled with ricotta cream). So delicious.
They have a large assortment of pastries and some typical Portuguese breakfast snacks. I recently tried the shrimp patties and the cod fritters ($1.10 each) and both were OK.
They have free wifi and decent coffee too. Lots of seating, clean enough, staff is usually good.
