A couple of ways, and one would be to tell us where you want help/what has to be fixed? Normally this is tasked by our mind-reading team but they are away at the moment.
once i start the program and type in the restaurant name, it just displays everything in quotation marks the it says "press any key to continue" and closes the program when i type a key
On line 6 of your program you have declared all variables to have type double. This means they are all numbers. restaurant, date, and the rest of the variables are numbers, so when you use cin to read a value to these variables it expects the user to enter a number. If the user don't enters a number it fails.
I guess you want restaurant to be of type std::string. That will allow you to enter the restaurant name as text.
