Eating Roti on the streets of Bangkok can be a warm tasty treat. Roti is a fried flat bread that is often served with many different fillings. The various roti vendors have different optional fillings such as fresh eggs, nutella, peanut butter, sugary condensed milk, and various syrups. My favorite is banana and egg, topped with condensed milk and a bit of sugar.
The Roti vendors are simple carts that crop up all over Thailand. So I recommend that you try one while walking off a great spicy Thai meal.
