We have a group of 19 people that would like to eat at your restaurant on Saturday around 3:20. Would we be able to make reservations or have room to sit together?

Call ahead,. I would say yes

My friend couldn't reserve a table for her birthday for about 15 people. She arrived about 30 mins early and they put a couple tables together for us. I would get there about 45 mins early for a Saturday.

I would call ahead and speak with the manager and let them know you have a large group and would like a section where ya'll can sit together so they can plan and try to accommodate as much as possible.
