Parked on the waterfront right next to the port is the famous "Yellow Bus". This is the place to get yourself something nice to eat (like maybe a roti -- a savory roll-up) and a cold drink.

The Yellow Bus serves good fresh food along with an amazing view

if you prefer something filling and sweet, walk just a little further north and you will see the "Fancy Jamaican Bakery". They bake a variety of interesting Caribbean cakes and pastries as well as brown bread and white bread. You can also get cold drinks here, including home-made ginger beer and the sweet creamy drink called "sea moss".
