If you're looking for outdoor bar ideas or DIY gazebo plans, this “grillzebo” is perfect. It's big enough to accommodate most standard grills but small enough that it might just fit on your existing patio. Customize your own grillzebo with lighting, grill accessory storage, wine glass racks or built-in coolers. http://www.familyhandyman.com/garden-structures/grill-gazebo-plans-make-a-grillzebo/view-all
The bar is open! Bar made from 2 x 4's skirted in 1 x 6 fencing and the bar top is porcelain tile on a base of plywood and concrete board. Under the bar is a refrigerator, my smoker, and a storage cabinet. All topped with a cheap grill gazebo flipped the long way. Fairly simple project that came out great.
