Restaurant dress code in Grenada
 

Will shorts and shirt be fine for most restaurants in Grenada? What restaurants require formal clothing?

I think the term "formal clothing" is misleading.

For breakfast/lunch shorts and t-shirts are perfectly fine in every restaurant.

In the more casual restaurants shorts & t-shirts will be fine at dinner.

At dinner most upscale restaurants prefer you wear appropriate clothing as follows:

For women - sun dresses, skirt & blouse or pants & blouse

For men - Khakis or dockers and collared shirts (golf shirts are fine)
