Osteria's menu focuses on simple and generous Italian cooking, with an emphasis on produce and seasonality, paired with reinvented Italian cocktails and regional wines. 

The lunch menu is available between 12–2.30pm, and offers regularly changing dishes at £14 for one course, £16.50 for two courses and £20.00 for three courses, making it the ideal business lunch destination at a very affordable price.

A pre-theatre menu is available at £22.50 for two courses or £26.50 for three courses. Served exclusively between 5–7pm, it has been specially created to offer the widest choice and ensure prompt service, so you can enjoy a relaxing pre-performance meal.

In the Aperitivi bar, the cocktail list showcases traditional Italian offerings with a twist, including seven variations of Negroni, Bellini and their signature aperitivo, the 'Mezzoemezzo'. The wine list includes famous Barolos, Supertuscans, and indigenous grape varieties by new generation winemakers from Puglia, Sicily and Sardinia.

Located on the second floor, the restaurant offers diners stunning views of the Barbican's estate.
