Chris Galvin just wants to get cooking again. The chef and co-founder of the group that owns Michelin-starred La Chapelle in the City and Galvin Windows at Park Lane worries it might be September, or even 2021, before diners return.

In December, La Chapelle had celebrated its highest monthly sales for 10 years; in January and February, Galvin said the restaurant saw 0.4% growth.
