We found the Grand vin & loved it. The atmosphere is casual and relaxed. It's not the largest wine shop, but you should be able to find something to enjoy. It does have a little wine bar for tasting. What really gives it it's charm is you can have your bottle decorked at the bar and take it outside to enjoy on the front porch. If you don't finish, recork your bottle & off you go back to your hotel (you might choose to walk it at this point + not sure of the legality of open alcohol in a vehicle or on a scooter, probably not a good idea). We walked.
Pros: great little porch to enjoy
