My workmates and I felt it worth the drive from Århus to Ebeltoft solely to visit the Ebeltoft Røgeri. The seafood is great, the have a great dark beer, and the staff is friendly. I hope to have a few more visits here. We loved the name, but it requires some British humour (sic) and an inside knowledge to explain--I'll skip the details.
Not quite Danish but this berbecue buffet you can sure check out. It says 'Spis hvad du kan' or all you can eat.
