Hmmm I don't think I've seen a coin mech on a Bartop,can you not squeeze it in the side?

Yeah not seeing the real value of having a coin door on a bartop, unless hes' gonna use it for a piggy bank as well, you'll have to open the rear door all the time to get the coins out as well. Typically there is always a space issue with bartops, where's your coin bucket going to fit?
If you wanted the full effect, i would of said do a mini bar-cade.....like this...its still small, portable and gives you the option of a coin door for the arcade feel.

I suggest a credit button, and call it a day. Putting a coin door on the side probably wont work either and you have to monitor brace to contend with.
The credit button will keep your build nice and clean....
