This is the hardest thing for me to do, but I have integrity and I believe it is in public interest to document when you have an issue with food at a restaurant; people deserve honest reviews.
I had a couple shards of hard plastic in my Pig and Pickle Eggs Benedict. These shards were hard enough to cause some serious damage if swallowed, so I'm glad that I am a good chewer. Although the service was stellar and the food tasted great up until that point, I'm sad that employees did not recognize and then throw away batches of food that might have been contaminated by a broken holding container.
I feel like two-stars is enough to document that this occurred for future visitors. I was compensated for my meal and I was happy with how this was dealt with, but I can never return.
