Corner Mercantile is an upscale, fast casual and healthy bodega. It's located right in the heart of downtown. Their sandwiches and re-heated prepared food are perfect for a quick lunch. The coffee/tea bar is also unique and serves great coffee. This locale offers products from company's both local and all natural.
This is the best quick grab lunch spot in downtown Pittsburgh, has mostly all natural products and is allergy friendly. I recommend this spot to all of my coworkers who work downtown.
