I feel like I posted this before but I forgot if I did and I can't find it in the old posts so... if so... here it is again!
On a visit to Barcelona two years ago I was taken to Granja M. Viader a dairy bar near Raval where Cacaolat was created (basically like yoohoo but better.) The specialty is simply the most decadent pudding like hot chocolate you've ever tasted. You can either get it with whipped cream or without (I got it with) and it's such a treat. You need about 4 cups of coffee to wash it down but it's worth it.
