@Jasmin Cottontail Yup, that's always entertaining too. And yes we can have food whatever we like. Yes it is kind of fun. @kaka135 Yes even I try outside food when I am travelling. Trying local area food is also kind of unique experience. But mostly during travelling on road or in train, we don't found good restaurants around always.. So at that time it is good to have home made food with us. After reaching to destination, even I like to taste the local food.
