Complete Hunts
Restaurants are where you can collect information about an area you’re in, buy some food for a quick stat boost, and take on hunting bounties. These hunts usually tend to be fairly simple (though they grow challenging later in the game), and they offer sizable rewards in the form of EXP and Gil.
To make your life easier, you’ll want to only go for the ones that say “Morning” or “Any Time.” Powerful demons roam the lands at night, and when you first start out in Final Fantasy XV you’ll find that they’re impossible to beat, especially when they’re in groups. That doesn’t mean all the daytime ones are pushovers, so you should still stay on your guard as you hunt.
Not only will you collect treasures from any enemies you kill while seeking out the unlucky monster on your bounty, but you’ll also get a decent amount of Gil and level up when the dust settles.
