You can find prepackaged brownies and choc chip cookies at many eateries. They're pretty good. I've been known to have a cookie and coffee for breakfast, they're a pretty good size!
There is a real lack of gf fresh baked goods (as in none), if you have Celiac (me!) or gluten intolerance. There are some things that are gf by ingredient, but due to cross contamination are not 'safe'. Be sure to check ingredients, and assume that anything that is 'dipped' is cross contaminated as I was told they dip cookies, etc, in the same pots. Likewise I ran across a 'flour free' choc cake where the baking pan was dusted with flour! Thank God for an astute CM who thought to check! Just do your own due diligence and assume nothing. I did have some of the English Toffee (made that day) from the Candy Palace and did not have a reaction.
After every trip I email GS and ask them to please find a supplier for one, just one, gf cupcake!!
