We're just back from a Spring Break trip and did mobile order from Panera for breakfast every day and it worked really well. Twice we ordered the night before, once we placed our order in the morning (website was down for maintenance at night). Always ready when we arrived (currently you have to ask for your order at the prep window, they are not currently placing orders in the cubbies for health reasons). We picked up on our walk into the park each morning and ate while we waited for rope drop. We also mobile ordered lunch from Panera before heading to the airport and were able to select a pick-up time only 10 minutes out.
