Pros
More intimate meetings
Unlike in group-based events
there are only two people at a table
Maximum connection number
If you make your event long enough,
everyone will meet everybody else
Cons
Waiting room
If there is asymmetry in attendee preferences,
some participants need to wait in a lounge area
Shorter meetings
Usually there are a lot of meetings, so you need to make them short,
not to exceed the event time limit
Longer event
There are a lot of rounds, and each
table
change takes time and introduces some chaos
High noise level
Everybody is speaking at the same time
