Never seen a bottle installed that way before. Looks like it would be awkward at least to take it in and out, but you said it works good. I like the pull handle option though seems pretty handy. Maybe add some of those plastic bins to the storage shelf to keep your little things like tips and stuff. Overall it looks like an awesome cart. I'm getting ready to build one myself as soon as I finish my table, and I would hope mine comes out looking as nice as yours. Oh yeah, diggin the diamond plate too, i'm gonna have to steal that one.
