Let's start with the most important... Coffee! Dineen makes a delicious latte. I've never had a chance to try any other drink here because I always go back for the latte. It might be a bit pricey, but it's worth treating yourself once in a while!
The service however is hit and miss. I've had excellent service at Dineen while other times the barista wouldn't even make eye contact with me.
I love the pastries as well! If you're going early in the morning on weekends, I suggest asking them if they can heat your pastry, as I've walked out with a cold (like out-of-the-fridge cold) scone a couple times.
It's an adorable cafe that's worth checking out if you're trying to avoid the brunch masses during the weekend.
