I'm not sure exactly what the dress code is but I think it's fairly casual, I went on a Saturday night with a T-shirt and a leather jacket on and there didn't seem to be any issues at all.
Causal very cool spot.
Just wear clothes... you should be g2g. Have the time people have kings jerseys on for basketball.. it's called Dive bar so all attire will work. Wear a tux say it's your wedding.. maybe get a few free drinks from people.
