How old is your daughter and does she have a contact allergy? The reason I ask is that Ohana hosts games at dinner time for kids. Since a peanut sauce is served to all tables, it is possible that there will be residue on the items or on the hands of other kids.
As for the meal in general, make sure to note you have a food allergy on your reservations. Your server will get the chef and they will go over what is safe for your daughter to eat. They will ask if you want the peanut sauce and the like brought to the table or not (some people still get it and just keep it away from the child... depends on the allergy I guess).
