    OK, I am planning on having a bar sink under the bar
    Or as we say in Mass, a "bah sink" :D

    It's an "L" shaped bar, 7' on the side that runs to the drain/vent area
    The sink will be located mayb 1-2' from that corner
    So a total run of maybe 9'
    Drain is not a problem, it can drop as much as needed
    But am I "stuck" with installing an AAV ?

    Or is something like this OK?
    The vent/plumbing would be much higher up as I won't be running down under the floor

    drain

    If you are NOT running it under the floor, how are you running it? Are you going to step over it when you go behind the bar?

    The sink will be in the left corner behind the bar
    There will be 12" cabinets/shelves along the left side of the L shape
    There will be a 3" open area behind the cabinets/shelves

    IMHO, Island venting would be the preferred method (though more complicated) rather than relying on a mechanical vent if they are allowed under your governing code.
