When space is an issue, a lot of attention should given to the flow of a space. Flow is important, but you should never lose sight of what the completed space will actually be used for. The objective is especially important to keep in mind when choosing an outdoor bistro set.  Gathering spaces work best when designed around a functional theme. This rule applies to both indoor and outdoor spaces. Entertaining takes on many different forms, so your outdoor bistro set should reflect the style of entertaining you are most comfortable with.
