Semi-solution for showing venues on the Dishes "show" page

I’m able to show the user name and associated venue for each person who
has favorited a dish, but I’m getting 5 instances of each item. I’m
pretty sure I’ve identified why— I think I’ve now seeded this 5 times.
I was getting 4 instances of each item and tried shutting down the
rails server, closing terminal, and restarting everything, and now I
get 5 instances of each item. Not sure how to remove the duplicate
items.
