Wow thanks so much for the info, much appreciated :) May I also ask how did you order the cabinets? Are they customer from a company or are they something I can find at a big box store? We really plan on trying to duplicate this but instead of wine racks there will be a TV, thanks so much for the motivation.

the cabinets are Home Depot Kraftmaid, the bar top is a custom piece we milled for the project.

If sitting at the bar, how much space is between the bar and wall on the left? This is a beautiful set up!
