The game is piss easy. hire staff till it is super fast. Then buy upgraddes but do NOT buy upgrades which increases the seats. The last upgrade should be the entrance (next to the alarm). Then wait and buy the service upgrade. Buy first restaurant and upgrade staff to super fast. Wait and buy second restaurant. Now its 3-1 in restaurants. Beat the last level 3 days before the end...
