Our story starts with Sully and Drake getting in their usual trouble as the game teaches you the basics of melee combat. After the first fight, you’ll end up downstairs for more fighting.
When you end up in the bathroom, be very careful and use the counter attacks only. Once the area is clear and you can walk around, find the first 2 treasures:
Antique Boxing Medallion
Find the slot machine in the corner across from the bathroom and you will find this in the coin tray.
Brass Vesta Coin
On the counter behind the bar.
Find one treasure.
After getting both treasures, head through the kitchen for another fight and exit the back door for a scene.
