DDC is extremely popular, and I can understand why.
They have a large selection of microbrew beers which rotate regularly. This place is often full, but it's not too hard to find a table.
The atmosphere is quite dark and loud, but it's a very relaxed place.
My only complaint is that their selection usually tends to be heavy on the stout and IPA side which can be frustrating if you are a fan of these beers. One advantage though is their flights where you can select three different beers to try rather than getting a pint of a single type.
If you are a fan of microbreweries, DDC is definitely a place to try.
