here's a quick start if you're having trouble. * = skip if you don't have it unlocked yet. Do the ground floor up through supermarket immediately when starting the level. Always make sure you have enough employees--it's worth it to have way too many rather than try to dig your way out of the 0% popularity hole (less guests with lower popularity, so it's very difficult to raise the popularity back up).
GROUND FLOOR:elevator,restroom,gadget*(substitute drugstore),books,tattoo*,burger,supermarket,ice cream,toy*,candy*,arcade*,restroom,elevator.
FIRST FLOOR:elevator,restroom,liquor*,steak*,cafe,ATM,jewelry,salon,boutique,music*,hall,restroom,elevator.
That should give you a good start.
