Yep, Duane Reade. They currently offer GF ginger snaps and animal crackers. As far as I can tell, they are cookies made by Midel and sold under the Duane Reade label (assessment based on nothing other than my taste buds - but I put a fair amount of faith in them). Wherever they came from (the Cookie Fairy?), they have been a godsend on many a long afternoon schlepping about the city. Sometimes you just need a cookie, damn it, and Duane Reade now it makes it possible to have one (or five) without breaking the bank. These usually retails for $2.99-ish, but I got them on sale for $2.49 in Brooklyn this week. And with Duane Reades now ALL OVER the city, you can get your fix in just about every neighborhood.
I often worry that GF items like these will be in limited production, available only in some locations of a chain - or will be phased out unexpectedly (see: Starbucks GF orange cake), so I have a habit of checking to see if these are in stock when I'm in a Duane Reade. I can honestly say that one or both have been in stock every time I've checked. In this GF life, the certainty of access to a safe treat is valued, even on the (very) rare occasion when you aren't in the mood for a cookie.
