I guess it would make no difference, just if they did say something it may hurt

A lot of restaurants have a bar as well. It's not uncommon for guys to come alone, sit at the bar grab some apps or wing and have a beer or two.  I dont feel ever weird about it or would I honestly care if they tried to be hurtful. Enjoy your alone time and just do you! It's your birthday, if your in the US it'll be your first legal beer! Don't waste the opportunity and go enjoys your birthday.  Happy 21st! 🎂
