Going to Mr. Onion is the closest I've been to being a regular anywhere. Is is a 10 minute walk from my house and the food is good and super cheap. Bonus - they are open on most holidays for breakfast and lunch.
The best thing Mr. Onion has going for it is it's breakfast. It is served all day and no matter what time you go someone is ordering it. They use surprisingly thick bacon and I've never not had my eggs cooked correctly. The eggs Benedict is the cheapest in town at $7.90. It is decent, but sometimes the hollandaise is a bit thin.
As far as dinners go, most of the meals I've had are good home style cooking. The main is usually good, but the fries, onion rings and salads are blah. Their "famous" pioneer bread is garlicky and smothered in butter - worth ordering.
The service is quick and friendly. I believe it is a family business and there are only a couple different servers. They are all very attentive, keeping up with coffee and water refills and quietly checking in on tables without being annoying.
So, if you ever find yourself in this pseudo industrial area at breakfast time, I highly suggest you check out Mr. Onion!!
