The Flour Box is a bakery / patisserie located at 5520 Rainier Ave S, Seattle, WA 98118. Here they sell what many would classify as the best donuts in Seattle. However, this place is so sought after that shopping for donuts here can be stressful at best. For starters, this bakery is only open on weekends for walk-ins.
On Thursdays and Fridays you must book online, to pick up your order a couple of days later. The process can be stressful for some, although many others will say these delicious donuts are worth the wait. But ordering online does not mean that you have already insured your donuts.
The Flour Box has a schedule for you to pick up your donuts, if you cannot pick them up, another customer who is there will have the possibility to take your order. So you have to be very careful and buy only when you are sure that you will be able to pick up your order.
If you want to avoid these bad times you can try a walk-in on the weekend, although you must arrive early and be among the first in line, the donuts in The Flour Box tend to sell out very quickly. It's not all negative though, The Flour Box is one of Seattle's best bakeries / patisseries, and their donuts are nationally recognized, so if you get a chance to order here, it might be worth a try.
