One way that people use the expression "You've GOT to ___" is to make enthusiastic recommendations of things.

In the example above, the speaker says that her friend "has got to" try the sauce because it's really good. Here's another example:

You've never been to the Met? Oh my gosh, you've GOT to go there! They have the most amazing exhibits.

This is similar to using "got to" to beg for something:

Please! You've got to help me!
