Does Voulez Bar have a table for 10? - I suggest the terrace on top of "Pizza y Espuma". It's across the street from Voulez Bar and could accommodate a larger group.
This is a good idea, if it gets too busy at Voulez we can go across the street. Although I'm hesitant to change at the last minute since many people may not see it. Lets try Voulez first and use head there as a backup.
