If we have made reservations and need to add one more place setting is that possible?

Man it best to try another restaurant cause thos place is not going for it

Call them back

As long as it's not for over 8 people you should be ok.

8 can sit at a table comfotably if you need 9 seats I would call and ask

I would ask unless you are taking a whole table. They can sit 8 comfortably at each station.

Better ask in advance
