>The most likely end result is the court finds your lawsuit is frivolous and simply dismisses it
You're completely right, the case will get thrown out. If you remember, in your scenario it is the restaurant suing the customer for not paying the 20% fraudulent fee, it's not the customer suing the restaurant.
Trying to add a fee after the price has been agreed and the food consumed is plain fraud. That's why they won't take you to court. If you dispute it while in the restaurant, they will let it go. Because they know the justice system will side with the customer.
Imagine for example if Ticket Master would charge extra fees after a concert, preventing you to leave if you do not pay. Not even they would do such a thing.
