Re: Open bar-like pass-through from kitchen to another room
That is generally called a "pass through". If you've got a major structural post in the middle of the wall, it may not be possible to create the open effect you're looking for. My first recommendation would be to leave the post and work around it, having a pass through on either side of it, however if it's not in the center of the opening, then it will not be aesthetic.
Another option would be to remove the post AFTER sufficient restructuring and resupporting has been done. Albeit more expensive and involved, this means would leave you with an unobstructed opening.
