Faced with an unfamiliar gastronomic landscape, tourists scouring the streets around Harrods see this quirky Italian as a sure bet – which may explain why it’s always packed. Although it’s been around for half a century & shows signs of ageing, Zia Teresa’s decor still valiantly tries to create the illusion of dining alfresco: its vaulted ceiling is painted to resemble the sky, street lamps adorn the walls & the open kitchen has a tiled, sloping roof. Plus points include attentive service from waiters in skimpy turquoise waistcoats & a list of aromatic house specials such as veal with orange juice & almonds; otherwise, expect the usual trattoria fodder including lasagne, spinach & ricotta ravioli, mozzarella salads & pizzas, accompanied by heartfelt Latin pop & a professional, all-Italian wine list with detailed notes.
