I really don't get the feeling they intended to purposely deceive anyone. I think this is really a case of printing the menu before they had all of the equipment and the financial reality of the cost to purchase the oven was more then they wanted to spend.

I would also say 19 Euros for a burger is a bit pricey for my pocketbook.

We seems to eat lunch that the Perch every day at 1:30pm. Between the happy hour 2 for 1 drinks and the $10 burger that made more sense to us.
