Deagan's only gets better with time, apparently. Been a few times (though not as much as I would like) over the past couple years and every time it's a great experience.
First and foremost, I would just like to put it out there that Deagan's is great about gluten-/wheat-free. Having a wheat allergy, it's a challenge to find places I can eat out without even a mild reaction. Their staff is on top of it, easily pointing out favorites that are gluten-free (all listed on the regular menu and they also have a GF menu with those specific items highlighted). They're great with questions and very proactive about making sure that everything stays allergen free.
What can I say about Deagan's? I've honestly never had a bad experience here. It has amazing food for the prices. The atmosphere is relaxed and can work for a variety of events from a romantic night out or happy hour to brunch with friends and family.
Most recently, we went for Sunday brunch and we loved it. The deviled eggs sampler in particular was stellar. Also really enjoyed the shrimp and grits. None of us were brave enough to try the Bloody Mary bar, but it looked great!
