For sure, you definitely want to feel satisfied, bu no matter if you're eating out or at home, you eat your food and it's gone. Sometimes there are leftovers, sometimes there are not. There are always dishes to do though, if you make it yourself. To me, the allure of eating out is you get to eat something you weren't going to make at home and you don't have to clean it up.
Regarding wine, you don't need to spend more than that, unless you're buying it in the country it was fermented. When my girlfriend went to Italy she brought me back a nice bottle of Chianti that I think was about $60.
I do think that you can get a different experience for more money though. I, for example, hate Gin. However, I like Hendricks Gin a lot because they ferment differently than other Gin. It costs about $35 a bottle, which is about $15 more than I'd like to spend on any liquor. Still, I'll do it for a special occasion.
