Should I notify someone ahead of time that I intend to have a group of friends meet my husband and I here on a Friday night for his birthday? I messaged them, but haven't heard back yet. I haven't been yet, so I don't know if seating is limited.

There is a good amount of seating inside and outside as well with patio tables. I would say since it's your husbands birthday it wouldn't hurt to let them know of the occasion and the number of guests just in case.

It's a good idea to let them know.

Update: I've tried to notify and haven't received a response. Tomorrow is the day. I tried.
