Roti Chai is located down a quiet back street near Marble Arch. This Indian street food joint has a simple cafe style dining area on the ground floor with a more formal dining restaurant below. The chicken samosas are crammed full of spicy chicken, the chicken lollipops are moreish and the hakka chilli paneer is one to go for if you can handle the heat. And wash the lot down with a lychee teapot cocktail.
