Just about the only time I go to the zona is on off days. I don't like the weekend crowds. But really any day you go to TJ is a good mongering day. If I had to pick the worst days they would be Monday and Tuesday, because if they girls are going to pick two days off they usually will try to pick these days. But then again, many girls work 6 days a week, so you can always find sometime. Since I have to go back to work on Mondays , it's also one of the days you'll see in in TJ. I say fuck work, I'm going to TJ! I can always find something, although even AB is a little slow on even Monday night. And the alley with the SGs are just seem a little slower, but not much.
My favorite day is Thursdays, as most of the girls are in bars getting ready for the weekend, but without the weekend crowds, same thing with Sunday, as the bars are packed with girls until at least 1:00Am in the morning, and then it dies down a little.
However, Revolution on weekdays is dead, except for a few South REVO bars, and during the day time in the zona is pretty dead too, with the exception being AB and Hong Kong. Tropical and LC will pickup at night.
