Where do I start? From soggy cold sandwiches to tasteless meat, I wish I had gone next door to the other sandwich establishment starting with a S. On a Bun makes underwhelming sandwiches that your little brother could whip up for you. The chicken does not taste like chicken because it is probably the frozen chicken breasts from the supermarket. The bun is probably the grocery store bun. Do yourself a favour and make yourself a better sandwich at home.
