invisible777 limited offering booze during the morning hours is pretty standard for CLs and not something that is related to the pandemic. If you're interested in
seeing the speakeasy, a little tour may be something you can finagle at the front desk. Amex is a customer service company after all and it never hurts to ask! In any event, even the basic amenities of this CL are really nice. I hope that you and your guest enjoy.
As for the VS lounge, I believe it temporarily closes at 8 or 8:30 AM and then reopens in the afternoon, so that likely throws a wrench in the recommendation above.
Another recommendation is the Delta SkyClub, which has an outdoor patio area that might be nice when you visit in the summer.
