Barcelona
Hi Melcocha,
I am not living there but have been many times.
You find a lot of dominican restaurants, colmados and money-wire agencies in Barrio La Ribera (just beside the Barrio Gotico), especially around Calle Sant Pere Mes Baix. We had chivo guisado with Presidente in Restaurante Puerto Plata and listened to bachata in one of the bars there. I am sure that you will find dominicans in Barrio El Raval as well, that is to the other side of the Barrio Gotico. There are dominican merengue discos on Gran Via.
Enjoy Bar'na.
