I had lunch at Mercury today. It was pretty packed around 12:30 but we were able to get a table. The burger was really good, the soup was meh. If I find myself in the area again I'd go back as they have a pretty extensive diner menu and it would be nice to try more of it.
I have and like it. They make a good burger and that's usually what I get. I've had some of the soup of the days and are also good. I keep meaning to head back and get deeper into the menu but haven't much lately.
