I love hot chocolate but I don't like Starbucks what are some places that have really good hot chocolate?

I just bought a Senseo machine and I know that there are coffee, cappuccino, and tea pods for this machine. However, I LOVE hot chocolate and I was wondering if I would be able to make any with my new machine?

So, about 4 or 5 years ago, i remember getting this drink from starbucks in the winter. It was like super rich, thick hot chocolate, practically melted chocolate in a cup. The cups they sold it in were really little because it was so rich. Does anyone remember the name of this drink and whether or not starbucks still sells it?

Can you put hot chocolate powder in an espresso machine and get any good results?
