Can I enter the store alone?

Yea, you can have a table for 1 but I'd try and sit at the bar so you can talk with other people.

I also had a great experience at the bar by myself

If you go by yourself sit at the bar. There is less of a wait than trying to get a table

You can definitely have a table for 1 or sit at the bar to have a entire dinner experience. I highly encourage sitting at the bar
