I love this place so much. It really does feel like going back in time. There aren't many places that can do just one thing, and do that thing well.
The service is friendly but to the point. This isn't a place you spend hours at. Just walk in, take a seat at the bar, and order a special, a milk cream (cola is delicious!) and some pickles. Be sure to add a little extra mustard if that's your kind of thing.
Don't ask for your special to be cut in half, or for any special requests. Just accept that this place has been around almost 85 years, making the same specials, and maybe the way they do things is for a reason.
