Vagamundo in Cabarete is still very good, Belgium Bakery also in Cabarete is consistent and the baked goods are excellent. There is a good spot for local coffee and chocolate on Umbrella Street in Puerto Plata, can't remember the name.
Nectar across from Ahnvee had very good coffee when it opened, but I can't speak of it lately as the wooden breakfast plates turned me off of going there.
Across from Baileys is a new coffee shop called Conti. They probably do the best job in Sosua right now.
I get an OK cappuccino at Mofongo King. Most other places I just gave up on.
