On the House Grenadine Syrup

"On the House Grenadine Syrup"...is 'on the house' a really good name for anything that gets used at a bar? Other than that, this is okay stuff. 

What do you really think about Grenadine Syrup anyway? I mean, how does this stuff come about? 

As it's made from corn syrup 'On the House' cannot be thought of as a high quality product. It gets the job done. I can't say much else.
