Okay thank you

Idk if it's the best but the way I did it was:

1. Wait behind the rock until the guards at the start have their backs towards you and run to the garage (Avoiding the guard close to the garage)
2. Honk the car honk in the garage, and crouch on the right side of the stairs waiting for a guard to come check it out, so you can sneak to where he came from.
3. From here go through the room with a little Budda statue, and then a small corridor, avoiding the guard patrolling it, and walk to the door at the right side, at the end of that corridor.
4. Walk through that room https://steamproxy.com/sharedfiles/filedetails/?id=3421862693 until you go to that door, look through the keyhole until the guards go away.
5. Sneak to the 2nd room on the left from there, there will be a Cook outfit, after u come out that door you can also visit the 1st door too and take the SMG with you, just to have it.

6. Go to the kitchen (through blue curtains), from where you look, at the end, door to the left, there is a poisonous fish there, go and cut it.
7. Go back to the kitchen, place the transmitter and the poison in the dish at the end of the table, then you can go to the exit immiediately.
8. Go through the door in the kitchen, where the last guard left to. And then when you're outside, walk right, you will recognize that you're at the beginning of the level again, walk to the gate at the end. You might have to wait a minute or two for the target to eat the food. But don't wait to close to it, so the guards don't get suspicious because they'll walk close to there. When you get a second Mission Update, you can exit.

What is the best way to complete this mission?
