I am going to build a website which is about to have a lot of restaurant, say 200 restaurants. i am going show the menu for every restaurant. and further items in menu.

1st Question: Should I hard code the menus and item details or should i use the database??

2nd Question: I want my website pattern something like that, if i click on restaurant "Pisa Pizza"
my URL should be like this www.myrestaurant.com/pisa_pizza/
and content of page will be all the details of "Pisa Pizza".
Further if i click on the menu button
my URL should be like this www.myrestaurant.com/pisa_pizza/menu
and content of page will be all the details of "Menu".

I am just confused, this way i may have to make a lot of sub directories, what should i do here. Because there are too much restaurants i can't make a separate for all of them.

And i am building my website in CODE CHARGE using PHP.

I will be thankful if any one give me idea and right direction .

Thanx
