So this is something I've been working on for quite sometime over the past few years.  It's 100% designed from scratch and built by myself.  The cabinets are walnut plywood to save on money and weight ($120 a sheet x 2).  I didn't want to use iron-on walnut edge-banding so I decided to cut 1/8" strips from a walnut board, it's definitely going to last longer and it looks great.  The bar top is constructed with a birch plywood base and topped with rough sawn walnut boards that I planed and joined down to 3/4".  There's a square hole cut out for the condiment tray and plenty of room for all types of glassware and bottles.  The walnut wine rack pulls out for other things I will build to put in it's place.  The finish is General Finishes Enduro-Var, which is the best water-based urethane on the market that has an oil like finished but dries in 20-30 min, is scratch and alcohol resistant.  The frame made from 1" square tubing and 1-1/2" round tubing welded for one solid frame.  The bar is designed to be taken apart in four pieces: Top, frame and 2 cabinets, so it can be moved anywhere.
