Laposa has an amazing view - definitely worth it to climb up the hill and get some nice shots. Wine, on the other hand, was not the best I've tried in this region. Me and my boyfriend got 6 wines tasting and we both agreed that the dry wines were rather 'generic'tasting and were very similar to each other. We both like dry wines and Laposa specialises in them so we had high hopes, but the overall experience was a bit bland. The wines were not bad - light and great for summer - but not characteristic enough to become favourites.
The service was pleasant, though not very personal - the presentation of wines seemed quite 'rehearsed'. In the end we regreted spending so much time in there rather than going to smalle, not such mainstream places.
Overall, if you want to get amazing instagram pics and drink a refreshing glass of wine that is known in the region - the place might be for you. If you're more interested to find something special - I'd say look at the smaller wineries that Badascony is full of.
