What's the point of having a reservation if they don't sit you right away? I just recently set up a 90th Bday dinner party for my mom with a 28 seat count at 4pm on a Saturday. Set up a month in advance. People were seated by 3:30-4:00. Walked my mom in to applause at 4:05! Fuck that waiting bullshit!
I waited an hour recently for a reservation. it was a small place with only a couple tables that could accommodate the size of our party. The people before us just chilled and drank and ate and chatted long past the 1 hour service time. They were a group of vets and it was the day before veterans day so nobody said anything.
