Popine is a pizza restaurant near Montmartre and Sacré-Cœur, across from the Atelier theater. It serves traditional Italian pizzas, including mortadella pizza with pistachio and burrata and a tuna roll pizza, along with focaccia and panna cotta. There are shaded outdoor tables and a terrace facing Montmartre. Ordered water can fail to arrive after two requests, and food and drinks can be an hour late.
