This is kind of contingent on the cost of tea, but a good homemade cup of loose leaf tea. Especially pu-erh or oolong. They can be re-steeped several times for maximum enjoyment, so it's totally mustachian, right? :P
Also, the act of cooking homemade meals at home with my husband is so fun, usually accompanied by great conversation, laughing, background music, and wine or kombucha. The drinks are extra, I guess, but all in all it's so much of a better experience than going out and being waited on!
