Hate to be hardcore but to really answer this question we'd need a floor plan of the venue, with labels for bathrooms, exits, trash cans, windows, and ordering counter. All are relevant to making a smooth approach.
Or you can just say fuck it and make a slightly "obvious" approach that should still be fine if you stick elderly.
