As I see it the beverage packages include unlimited red and white wine, beer, espresso and soft drinks. We have to make a group decision whether to take a beverage package or to go a la carte with drinks; everybody ordering what they want. If we want to stick to beer, wine and soda, I think this is the most economical way to go. We would just have to decide what quality level suits our budget.
I also like the 6:30 time for the reservation.
