mousecrazy is right, I went with my brother for his birthday last month and now they give out buttons. They're really cool buttons, too.
I checked the calendar for Friday (I'm going Friday) and it says the Tortilla Factory is being closed for refurbs.

I hope you get to go tomorrow though, those tortillas are the best. My friend and I went for our birthdays (we're four days apart) and we both got tortillas and then ate them with the skewers from the Bengal Barbecue while waiting for the fireworks. GOOD TIMES.
