Tables for mitigating infectious disease spread are disclosed having at least two seating areas that are configured to minimize the transfer of aerosolized droplets among the seating areas. Between each seating area are a series of impermeable barriers—at least one hanging impermeable barrier that projects downwards towards a top surface of a table and at least one rising impermeable barrier that projects upwards away from a top surface of a table. The impermeable barriers are disposed to overlap one another along a line of sight between seating areas such that a bottom edge of the hanging impermeable barrier is at a height above the top edge of the rising impermeable barrier. Vacuum mechanisms can be positioned above the hanging impermeable barriers and below the rising impermeable barriers to create airstreams along the impermeable barriers that guide airborne particulate matter blocked by an impermeable barrier into a vacuum mechanism.

In accordance with an embodiment, a serving presentation system includes: a mobile cart comprising a cart housing defining a cart cavity, a first port in the cart housing, and a cart conveyor system disposed within the cart cavity that may convey a serving from the cart cavity toward the first port. The serving presentation system also includes a table including a table housing defining a table cavity and a table surface with a table top port that may receive the serving therethrough, a second port in the table housing that may align and/or engage with the first port to define a passage between the cart cavity and the table cavity, a table conveyor system disposed within the table cavity that may convey the serving into the table cavity from the cart conveyor, and a lifter that may transition the serving from the table cavity through the table top port.

A smart dining bar includes a tabletop unit, a refrigerator refrigeration unit, and a control unit. The tabletop unit includes a small table top, and the refrigerator cooling unit includes a foamed door body, a storage rack, a lifting assembly, and a refrigeration chamber. The small table top, foamed door body, and storage rack can be raised or lowered along with the lifting assembly. The foamed door body is detachably mounted to the small table top, and the foamed door body is detachably connected to the lifting assembly. The dining bar is equipped with a refrigeration unit, which not only fulfills the basic function of a dining table but also provides refrigerated and frozen storage. The lifting column racks allows for easy access and maximizes space utilization. The small table top and foamed door body are detachably installed, and the foamed door body is detachably connected to the lifting assembly.
