We went there to get a bite to eat about 10 minutes before their arbitrary end-time for lunch, and the owner, very rudely, yelled that if we didn't have a reservation, we'd have to leave.
Now, I can definitely understand being a lazy business owner with a captive audience in a tourist trap, and not wanting to make more money by serving more people. More power to you and your comfort taking precedence over money. Seriously. Good for you! But, don't be rude about it. Fake a smile. maybe throw in a "desole" or something. Avoid this place.
