Getting Started
Makung A Restaurant rake a really long time to get the profit. But after gaining a positive income, you can open another branch.. woohoo.

Step-by-step Tutorial

First of all DO NOT hire any employees until you have rank 3 business.. How to survive it? you need "Sleep on Business lot" hack, "owner/employee auto refresh" hack. and "Simlogical PayBuffet"

- The first day, you just need to buy Simlogical paybuffet at your lot.. and you an set electro-ticket-machine (ETM) for free... this will give you some money while increasing your customer loyalty..

-same goes to second and third day (this time you can set cheap price on ETM)... The trick is.. When your customer take a foof from the buffet, join them... eat with them, and build relationship with them.... After they finished eating.. chat with them.. and make some friends ( I suggest you use Autosoc hack from MATY)

- After day 5, you suppose to have rank 2 business.. and some income.. here is when you start your business.. buy a podium, chef kitchen and some more tables.. do not I repeat DO NOT hire employees yet..

- when customer come, click on the podium and assign yourself as " Host".. and then give menu to customer.. after they decided what to eat.. click at podium again and assign yourself to be a " Server".. then your sim will seated the customer and chat chat.. and they will ask the food.. .. Click at the chef kitchen and click ' Become Cook" and after few sim minute, they will finished coooking.. click on the podium again and assign yourself as "Server" again.. then your sim will pick the food and serve it to a customer..

- The tips is.. you must put the table mear kitchen.. do not place table fay away.. if you do that.. you will lose a customer loyalty...

- Reporter are always come to the restaurant (maxis made it that way).. so.. organised your work.. .. hehehe.. Sometime I even get Three (3) reporter at the same time...

- if you reached rank 3, Hire someone to be a host.. and your sim can be a cook as well as a server..

- After rank 5, and you have positive income ( $20,000) and you can hire someone to be a server, cooker,and someone to clean up all the plates..

- If you have servo on the lot.. they will automaticle clean all the plates.. "yahoo" .. and after they finished it.. click on the servo and choose "Power down".. this will make the servo stuck on your lot.. and when the're a plate to clean, click on it and choose 'Power Up" again.. So what do I mean is.. you don't have to hire anybody to clean up..

- After getting rank 7 business.. you can hire someone to be a manager.. and relax at home and let the money come every night .. (use "hire anyone to manager hack" and "anti Business Decay hack")

- and then you can open a new branch in a new place again...

- for business perk.. I Suggest you unlock the "connections" and "money" first.. the other may not be very useful except "rally Forth"...
