[The pizza took off and fell on a customer's face because I didn't have time to warn him.]

In the center of Havana, there's a pair of entrepreneurs who are taking pizza delivery to new heights.

[I'm Marta one, the older one, and she's Marta two, the younger one.]

[Two Hawaiians.]

[How much longer for the cheese and onion?]

[They're on the way? Great.]

[At first, we carried the pizza down the stairs. This would tire us out.]

[People started giving us all kinds of ideas until someone suggested we lower the pizza from the balcony in a basket.]

In 2010, Marta number one and her husband were granted a private business license and opened up a pizzeria.

A few months ago, her husband passed away.

Now her best friend is helping her keep the pizzeria alive.

[The pizzeria's called A Mi Manera because you order the pizza the way you want it and we make it.]

Since then, the pizzeria, which operates from Marta number one's roof, has filled countless stomachs with their secret recipe.

[The key to the taste of the pizza is in the dough and the sauce.]

[Every pizza maker has their own sauce and dough.]

[They don't reveal their secret.]

[We've tried to be consistent with our dough. Here it's handmade.]

[The quality of this pizza is indisputable. People come form all over to eat our pizza.]

[Pizza helps Cubans survive and persevere.]

Ever since Marta number two joined Marta number one in business,

the two have formed a true partnership.

[The two Martas can do whatever they feel is right.]

[Either one of us has the power to decide what's missing or what needs to be better for the business.]

[I always try to do things while laughing because laughter brightens up the day.]

[A smile is tremendously valuable.]
