This is how the great fast.ai course begins - download VGG16, finetune the top layer with a single dense layer, get amazing results. The second or third class shows how to make the top layers a bit more complex to get even better accuracy.
What do you suggest for someone who has experience with Deep Learning?
EDIT: found this wiki with the course notes: http://wiki.fast.ai/index.php/Main_Page
One can use it as a guide to avoid missing anything.
