Tourist Guide HELP in OAHU Pretty please :D

Always824

So its almost 11am here and tonight around 5:30pm I will be showing a friend of mine from Guam around Oahu... I know, timing isn't that great but he was only here for a short time for a conference for school and this is my only time period to show him around before he leaves tomorrow...

So far, he has already seen:
Waikiki
-Alamoana Mall
-China Town
and
North Shore
(Sorry if the grouping sucks lol)

I've been here for a while with my husband but because of his work schedule we don't go out alllll the time to see whats up... hopefully we will before he leaves but I just feel super bad because I really don't know where to take him on his liberty time due to the time slot... I mean, I would have originally shown him some hiking spots but heck no if I'm hiking at that time slot LOL

So please, if your from here, lived here and know whats up, and know of any cool places to show a friend from around 5:30-9:30pm please lemme know... ALSO, an awesome, moderately priced restaurant to eat at... Please lemme know,,, Thank you in advance
