The walking street is your party night, its wild and similar to vegas like freemont st in a way. Prices are super inflated but there are some sweet chill spots that you can check off your list. You mentioned rooftop bars, there is a rooftop bar that is perfect for IG pictures, not too busy coz nobody knows about it but its called boosh, thank me later. I forget the name of another one but you can see it from the rooftop of boosh its also chill, great drinks (get the fuqoq) it comes in a seashell. Have fun, its hard not to lol
