Insomnia Coffee Shop Dublin

Coffee Shop of Dublin that is not Starbucks or Insomnia …?

I spent some time in Dublin a few years back and met my husband there and we talked the other days trying to figure out the name of the popular coffee shop that is around Dublin, and we can not think of the name? There is a lot like Starbucks and Insomnia, but it is none of these. I think it starts with 'O'…. Can anyone help me. It drives me crazy. No, I do not know it was Bewleys, and there was only one word name … with a first paragraph (which I think was O) separated from the rest of the word. O'Briens! Thanks! And yes, you're right, it's more of a sandwich shop, but I remember it only for the coffee …

I'm almost positive it is O'Briens. But it would be a sandwich bar more than a coffee shop so maybe I'm wrong.
