7. Interesting development: Small-footprint DIY herb garden
As another play to sell sustainability, as well as a front-of-house talking point, one supplier rolled out a refrigerator-looking unit that allows operators to grow their own herbs, lettuces and microgreens in-house. Each compartment (the unit is four compartments tall) can be separately programmed via a touchscreen to supply the correct amount of light, water and temperature for each shelf, creating different zones to grow a variety of greens.
