Several years ago I took a girlfriend to PizzaExpress and my mates turned up and laughed at all the couples including us sitting on tables for two with something as unromantic as pizza.
I recommend staying in and cooking your own Sunday lunch - much better than any pup food I have experienced! My favourite is pork with perfect pork crackling! Yummy.
I had solar panels fitted a few years ago but then got forced to move house due to financial pressures and obviously wasn't able to take them with me! Make sure you know you are going to stay in your house for quite a number of years.
