Upon first glance, Deagan's seems a little douchey.
Its mostly filled with uppity white people, its always pretty loud, its not really a gastropub, and generally there's a decent wait.
HOWEVER
The staff is so nice! The food is tasty and you get it fairly quickly! There are some great beers on tap! They have a vegan/vegetarian night on Wednesdays! Even the dessert is good! Exclamation point city!
I honestly couldn't ask for much more out of a cocktail/kitchen joint. Its a tasty-good-time and I'd definitely go back.
