Since we were already in Westchester (and it seemed a waste to pay the bridge toll just to turn around and try again) we checked online to see what was nearby. 97lake (review) wasn’t too far, and neither were the Golden Wok Cafe, or the By The Way Bakery. The friend I was with is very gluten sensitive and also has a lesser issue with tapioca so we decided Golden Wok might involve a language barrier that would be more than she was willing to risk (especially with an hour drive home).
I ended up with two dairy free / gluten free cupcakes – a vanilla with vanilla icing and a carrot cake. They both handled the trip home (as you can see the icing on the vanilla banged around a bit, but it was still delicious)! I also found their prices to be reasonable, especially for a dedicated bakery.
Oh, and the staff was able to recommend a great restaurant for us: Maud’s Tavern (review) which is about two blocks away!
