home is where the bar is
Nothing says welcome to my home like a "Welcome to My Home" welcome mat. But beyond that, how else can you ensure your guests feel comfortable, relaxed, and conversational? Have a fully loaded bar with all the requisite spirits and barware that'll make you look like a full fledged mixologist (mustache and suspenders optional, of course). For less than $300, you should be able to find everything you need to put company in the proper spirits, so to speak.
