Hello - going for a quick trip the weekend before Christmas and it is just my DS and myself and his favorite is 'Ohana...anyone every just walked in at 'Ohana and got a table for two without ADR?
Keep trying for an adr, your chance of walking up are very very slim. If you do walk up be prepared to be turned away, or at the least have a 2+ hour wait.
I guess I've been very lucky. We've been able to walk up 3 times and get a table. Waiting time was less than 30 mins. too. I tried for an adr for months.
