Some would say thank Heaven for bars when you have to wait to be seated. Joe's is like that. A very popular place that doesn't take reservations.
I have acquaintances you tell me that they didn't like the wait because they didn't want to wait in the bar and spend money drinking. They were hungry and want to sit and eat dinner.
So, I don't know what to tell you except, I'd go during non-peak hours. Call Joe and ask him when that could be.
