Susan's Lunch - Sleeping Dogs
After the mission, you have to do a favor for the nearby vendor to gain Face. For this particular favor, you have to deliver the money to the Golden Koi, as marked in your map. On your way there, you'll be attacked by thugs. Avoid getting surrounded and use counters and environmental takedowns to get rid of them. Talk to the cashier to complete the favor. Head to the kitchen next to talk to Winston.
