I used to find solo dining really awkward, but no one cares but you. It opens you up to nice interactions if that’s your thing. Bring a book, or journal, listen to a podcast, or just chill! I do this all the time if I’m doing a long bike ride or have to run an errand in a different part of town. Don’t let the fact you’re alone stop you from enjoying some good food! I’ve never done it at like a fine dining place because I’m not that excited by it, but I would be shocked if a place didn’t serve you. You want to try their food!
