Our reception space can accommodate 120 people guests seated. We do not have a final count but it is possible we may have 150 guests. The reception venue suggested food stations instead of a buffet with no assigned seating. The venue is in a city art gallery so the vibe is definitely modern/somewhat formal. . Has anyone in a setting such as this gone with open seating.? What if more guests wish to sit then we have seating? How do we manage tablescape when we do not have seats for all?
