I tried to access Ambiance for the longest time - over a year transpired before I was able to actually get to the store when it wasn't closed (I always make the mistake of assuming coffee shops are open past 9-5 business hours). When I finally got past the front doors, it was worth the wait to try the heavenly hot chocolate that had been long recommended to me by many friends. It was absolutely decadent - SO dark and rich (apparently it's made with 55% valrhona chocolate and 35% cream, which makes for QUITE a lethal combination, in a good way) that it most definitely leaves chocolate stains on your lips. An amazing indulgence!
