Yes. Typical built-in storage options include multi-tier shelves and large under-table shelves sized to hold dishes or everyday items.

Set configurations range from 3-piece up to 6-piece; seating options span 2 to 6 seats. Many compact listings show 4-seat (often 5-piece) arrangements as a common small-space choice.
