The weather forecast for Wednesday in Chicago calls for a low of -22 degrees, and thus restaurants and bars have started to announce they’ll be closed on hump day. The announcements started on Monday afternoon as Chicagoans dug themselves out of about two inches of snow. This time of year is traditionally slow for restaurants, and many owners would rather keep workers at home rather than risk frostbite.

This may put a wrench in Restaurant Week Chicago, as the Choose Chicago’s promotion started on Friday and goes through February 7. A few participating restaurants have announced they’ll be closed on Wednesday. The historic cold could also lead to no-shows.

For those who think food delivery is invulnerable, think again. A GrubHub spokesperson writes that they’re keeping an eye on Chicago’s temperatures and “restaurants may continue delivering food upon their discretion and amend their hours to ensure the safety of their staff.” They’ll also institute “temporary pauses” to services to ensure staff safety.

A Caviar spokesperson expressed similar sentiments about monitoring the weather. They added that they’re encouraging bike couriers to switch cars. To further encourage car deliveries over bikes, they’re only offering delivery incentives to car couriers for Tuesday night.

Update: Caviar isn’t offering delivery on Wednesday.

No matter what customers should be patient. And they should tip.
