Yes, unless the store owner has a compelling reason for it not to be, it is out now, so it will be legal.
Please be aware if you intend to attend this event, this store has a hard cap on capacity. To ensure a spot, you MUST sign up in advance on their eventbrite page.
No charge to sign up, but there will be a $10 fee on site. If you haven't been to this venue, you are missing out big time, fantastic location (right next to the Metro) and myriad lunch options in walking distance. Show up early and check out Eastern Market, it's great!
