Perhaps this is custom made.

Something of this size is probably custom made, especially with the thick butcher block top. You can pull together a similar look yourself with cabinets, legs, and butcher block top though.

Try chop-block.

Hi,
I could make this for you. I am in Alameda CA, and specialize in industrial and rustic furniture. What are your desired dimensions and material? I could make some reclaimed metal legs if you are into that look, or I could make them out of wood. Let me know if you still desire this. Have a great evening

You rarely find something like this for sale online. Shipping on something like this would probably cost 600 dollars. I would definitely say go to a local cabinet maker.
