I have been around this map multiple times and cannot find the liquer store. maybe a indicator as to what direction it is in? It is also difficult to control the car. But again, I do not play a lot of vehicle games.
I added the indicator to help show where to go~
As for the car control I followed a tutorial that uses something similar to how old GTA games used to be controlled.
It takes a bit to get used to haha!
