Service on the terrasse is next to non-existent. Waited 10 minutes to see a waitress, as we were getting up to leave, one showed up and was surprised we were leaving.
The service on the terrasse is the exact opposite of indoors, where you are served promptly.
IMO if you want to spend time outside, find somewhere else, as you may die of thirst and/or hunger first. if you want to go inside for a drink or a meal, than by all means this place is great.
