It was super informative and a fun experience. I wish we would've had a little more time to try the food/wine or an option of having the leftovers from the tasting packed up with a few other things to take for a picnic later. Our guide Alexandra was excellent!
We went at night and it was hard to see much, but worse was the audio. It was on a loud speaker going between 4 different languages and was really difficult to hear. It made the trip a bit frustrating instead of relaxing and informative. I wouldn't pay extra for champagne next time either.
