Pastelerias Princess

We got takeout coffee and snacks here. One of two Pasteis de Tentugal we got (the first we tried) tasted a bit moldy, and when we opened it up to investigate, we find the filling surrounded by a dark gray layer. The second one didn't have that and tasted fine. The other pastry we tried had a creamy filling which had a bit of an unpleasant bitter aftertaste.We took the remains of the moldy pastry back the next day to let the owner know, and he didn't even address us directly, just told his assistant that that filling sometimes gets a great coating around it but it's normal and not moldy. He was uninterested in hearing that it had tasted gross too and was clearly not ok. There was no offer to compensate with a replacement pastry or to refund our money, not was their any acknowledgment from him that we had a legitimate concern.I would never buy food here again.
