Not enough information-need dimensions and a bit more about your preferences

They can be oval too, if you have enough space,

But give us more info maybe, so we can be more useful

A few general guidelines...
-round tables are easier to walk around as there are no corners/chairs can also be placed on a diagonal to allow for more space
-chairs should have enough space to be pulled in/out comfortably without hitting any obstructions and to allow an average sized person to sit without feeling boxed in
-consider a table with a leaf if you want the flexibility of entertaining
