I've been surfing chow hound on/off for years and I think it's finally my time to contribute.
There is a chocolate kiosk near the Barnes & Noble at Stamford mall called Raaka. And good news! They don't use any nuts, dairy, soy, or gluten. The gluten and dairy bit is a big deal for me as I have some sensitivity. SERIOUSLY. And more good news for keto and paleo chocolate lovers: It's basically raw and they have a low-carb/extremely low-sugar bar.
Out of curiosity, I started breaking up a bar and decided to bake it in some muffins. Absolutely no regrets here.
You might want to go check it out this weekend while they're still there. Enjoy!
