What about two separate pieces like this? One would be open for the fridge and the other could have shelving inside? I'd bring the outside panels over the casters & do the bottom in white & the top the butcher block or wood...
DIY - Sideboard / Buffet Table. Farmhouse Barn style hanging doors, painted Annie Sloan Pure White and distressed. Top was made from 2x6's the were squared and routed and painted French Linen from Annie Sloan. Hangers were made from 1/8 flat bar and sliding doors wheels from Lowe's. I used square bar from Lowe's as a rail at the bottom and painted it black. I used screen door small plastic wheels on the bottom of the doors that fit into the track to hold the door in place.

The furniture pieces on the wheels are easy to transfer anywhere as there is no need to pick them up by hand, this giant wood pallet bar idea is great for those who are planning to open a bar. The size can be decreased if the bar area is not spacious.
