At the most, i consider my home bar full when I have 4 bottles of booze (rye, bourbon, vodka and tequila), six-pack of beer, six-pack of coke, Sweet Vermouth, bitters, soda water, lemonade, orange juice, and Bloody Mary mix (that I never use).
My house has a utility room that I've converted into a bar because I'm the only one that uses it anyway. It's got all my carpentry tools, yard tools and a small file cabinet for my comic book collection, lol.
The most important thing however is a lock from the inside. No one outside can get in if I lock it from inside. There's no key, just a small hole in the knob that, if you know what you're doing, you can unlock with the right type of tool.
I can go in there, sit down on my bar stool, at the table, pull out a glass and just drink, read and write in silence.
