Brunched with my HO pal this morning at Union. Air flow re: CO2 was pretty good, 650 - 1032 while we were there. In comparison, my favoured coffee shop’s reading was over 1800. Ideally, it’s safest ventilation in terms of air being exchanged , if the CO2 is less than 1000. When I’ve brought my CO2 meter into sealed patios, the reading has sometime been as high as 2200, which means very poor ventilation.
Union is my favourite heated patio that’s open in January and February. Most heated patios are either sealed in plastic, or closed when it’s less than 10 °C outside.
I had the Swiss Train Ride Croque ($22 CAD) and she had the crispy polenta with eggs ($23 CAD).
