On the Grapevine is a fantastic little wine shop that lets you choose your bottle and drink it right on the premises for only a 7 euro corkage fee. There are ample sitting spaces in the main shop as well as upstairs. They also serve food like tapas, sandwiches, and other snacks. There's even an expresso bar.
The best part is that because they are a wine bar you may request a complimentary sample of a wine and then purchase the bottle and drink it right there. Many wines are even 20% off or right around €10 for a bottle. We stopped in because it was raining but ended up finishing the whole bottle and even contemplated getting a second bottle but the weather had cleared so we were off to continue our sight seeing. Dangerously fun but strongly recommended. read more
