Where Is The Best Place To Busk Guitar Or Violin To Earn Tips?

I seem to make a lot of simoleans at the bars.... I guess there's a lot more foot traffic in a bar setting than there is anywhere else? Just so long as you setup either inside the bar or right by the main entry/exit door.

I find that parks, festivals, etc don't seem to have as many sims walking around to stop and listen and throw you some tips.
