Restaurant names are critical.

A good one could be the difference between a diner taking a look at the menu — or moving on.

So, in episode 5, we explore why names matter and how restaurants can choose the right one.

First, we take a lighthearted look at how some top restaurants got their name — from the Latin American eatery that shares its name with a Kanye West album, to the pizzeria that found its name in the English-Esperanto dictionary.

Then we talk to Amy Dennis, of the Nice Branding Agency, who helps restaurants come up with a name and says that "naming is probably one of the hardest jobs we encounter".
