When I lived in Dublin, Diep Noodle in Ranelagh (now takeaway/delivery only it seems) was one of my favourite restaurants (although I only went a handful of times), so I was keen to have my dinner at the Diep Noodle Bar.
The Menu is quite simple (and a bit more expensive than the current one on the web shows) but it's still hard to choose when everything is so nice. I remembered the yellow curry with particular fondness - it is still the one to which I compare all Thai yellow curries (and usually find them wanting) so I opted for the beef variant of:
Gaeng KareeIt was so delicious that I forgot to put my iPhone to its proper use of taking food pictures. Every bit as good as I remember. If you are travelling through Dublin Airport around time for dinner (or lunch) then I recommend planning your inward/onward journey around leaving time for a visit to Diep Noodle Bar in Terminal 2. (The meal arrived really quickly, so you probably don't need to leave too much time!)
Yellow Curry with Potato, Onion & Crispy Shallots.
One of dinner companions had a cappuccino and reported that it was very nice - made behind the counter at Diep rather than just coming from an automated machine. It might have been less than €3 too. This begs the question as to why they make the coffee machine so prominent but perhaps my poor awareness last time was more to blame than the setup.
