A successful date increases your 'like stat', and afterwards the girl may invite you in for some "hot coffee".
You should also consider the girl's likes and dislikes listed in the profiles above - adhering to these will further increase your 'like stat'.
Each girl has an 'initial opinion' of each activity that is available, and each time you take her to a specific place her opinion of it drops by 5, while her opinion of all similar places drops by 1.
For example, if you visit the Cluckin' Bell in Star Junction her opinion of it drops by 5, while her opinion of all other Cluckin' Bells in the city drops by 1.
