The restaurant offers Indian barbecue style meals and has live grills on the tables. The survey findings revealed that the majority of respondents were unsatisfied with the restaurant’s temperature, humidity, and general IAQ, while being content with ventilation, green spaces, and sustainability requirements. However, the measured data revealed that the temperature and humidity levels were within ASHRAE standards, however the air velocity and CO2 levels exceeded ASHRAE standards. Furthermore, PM 2.5 and PM10 concentrations surpassed WHO guidelines.
