Hello.

We are doing some basic DIY at our home and there is a cabinet in the
wet bar above the counter top. Its a 2ft x 2.5 ft wine rack flanked
by 2 42 inch cabinets

I see 3 screws on the side of the cabinet going into the wine rack.

Would it come off or is it nailed / glued to the wall or sides

Usually cabinets are attached with screws, not glue.
Each cabinet is screwed to the one(s) next to it and the wall.
If you don't see screws in the back, look for little plastic circles
which sometimes cover the screw heads.

Be careful to support the cabinet before removing screws.
Best done with a helper.
