If you go to the Grande Mosquée for tea, you will enjoy a sweet, hot beverage that warms you in the winter and refreshes you in the summer. A nice gentleman will pass through the courtyard with a tray-full of glasses like those you see below. Wave the man over (it may take several tries - he may be busy shooing away the pigeons), ask for one glass (or two), and hand over two euros per glass. Pastries must be ordered indoors.
In poor weather, you might want to head inside to the vrai salon de thé where you can enjoy even more vivid decor and a more bustling scene.
Panda didn't join us on this expedition but we're always scoping out future dog-friendly outings. From what we can tell, you can bring your dog to the Grand Mosquée as long as you take your tea in the entrance courtyard. But they made it very clear: no Cocker Spaniels or terriers allowed inside.
