I have since discover that any water draining from the kitchen sink is flowing back up from the wet bar sink drain and causing it to fill up. This is new as of yesterday. The wet bar sink eventually slowly drains on its own, but plunging and pouring boiling water has done nothing. It is also the only fixture in the house that is doing this. I am guessing this problem is downstream of both sinks which is why the wet bar sink is filling up with water from the main floor sink and also slow to drain. I attempted to snake it, but I think the snake is just going the wrong way probably heading up instead of to where the blockage might be.
I noticed the pipe on the wet bar sink was sloping down towards the p-trap, which I adjusted.
The wet bar was roughed in when we bought the house, so I assume it is all properly done. I only installed the sink to the drain there. And it has been fine for the last 13 years or so.
So, would this be a clog or should I be looking at something else?

Sounds like you have a clog downstream of both sinks before the main line. I'm assuming no issues with this when toilets are flushed or tub/shower drain? Sounds like your wet bar joins up with the kitchen line on the way to the main. Get to your main stack and see if you can find where the sinks enter, if you absolutely can't get a snake in from the drain side you may be able to get in from there and work backwards. If the basement sink is filling when any other sources are draining, your main cleanout is probably where you want to start.
My friend had roots in her main line and it took a long time to notice because the water sits in the stack and seeps out, hiding the problem. Water in your basement sink could indicate the entire drain system in full to that point, but then you would see it any time you drain water. your's sounds more localized indicating a midstream block.
