A new coffee shop and gourmet grocery called Foodgame recently opened up near Ringsend in Dublin. I've been in a few times now (in fact, I'm currently the mayor on Foursquare) and the owner is so friendly and enthusiastic about his business that I'm really rooting for him to succeed. So far, I think he's developed a winning combination -- an excellent latte that doesn't cost a fortune.
The coffee is 2 euro by default and they often run a promotion where the coffee is free (limit 1) if you order in Spanish or Gaelic. I love this creative approach. We had fun trying to muster up enough español to place our order. We did our best and our broken Spanish got us a Buy 1 Get 1 Free deal. I like that the owner is a good sport. Definitely stop by if you live or work in this area.
