We were there last night. At 9, the two of us tried to get a quick drink before our 9:45 ohana reservation, but the wait was 30 minutes. After dinner, at around 11:15, we walked in with no wait. The entire bar was open and several other seats were available.
Had a good time. The crowd was rambunctious though, and it definitely had the feel of a "cult classic" type place.
Also, I ordered the Pearl drink and asked for no cinnamon. She said she couldn't change the recipe unless it's a medical reason. So in she puts the squirts of cinnamon syrup... Ugh. Drink would have been great without the cinnamon.
