I would identify as a loner. My loneliness is not really by choice but also is in that it's the most comfortable bad habit for me to fall back on. I live the life of a loner by going to see movies, going for hikes and exercising, going to the library, doing crosswords- all things that can be done alone and for cheap. It's fine, it's comfortable, but I also know myself and that there are many times when I would prefer having some company. Having close, personal friends is a luxury I am currently without but I am always working towards making connections with people.
I respect anyone's choice to live a more solitary life, this is just my take. I remember going to see a movie once in a big city on a day when I had nowhere to be and nothing to do. It was some sort of early matinee..11:30 or noon.. and I assumed I would be the only person in there. There were actually some patrons scattered around the theatre when I first sat down and then a few more people trickled in. As the film started I looked around and realized every person in there was a middle-aged single man with some sort of bag. And there was me in my late twenties, my backpack in the seat next to me, and I made a note to myself not to never end up like that. They may have been perfectly happy guys but I am working towards having more people in my life, not less.
Food-wise I like to eat out and try different cuisines but I prefer eating at specific casual places where my singleness isn't as amplified as it would be at a fancier sit-down restaurant. Taco stands are my jam, Vietnamese banh mi shops, empty Indian restaurants, Peruvian cafes just to name a few. Going to bars alone is iffy for me- if I was more capable at flirting or striking up random conversations I would probably feel different than I typically do which is somewhat awkward and gratuitous (I'm not really a big drinker).
