This is a classic diner. No pretence. No fancy menus. I like it.
Starting at $6 you can get a full breakfast with coffee (and free refills). Also included in the price is friendly service (when is the last time my waiter called me a sweetheart?) and a chill atmosphere. I went around 930am after deciding I couldn't work another minute without some caloric intake. Luckily Johnny's G's is only 10 min from where I work. The tables were half full. People were lounging about, reading the newspaper, enjoying their refills. There is also free wifi. The tables are wooden and comfy.
My breakfast was filling. I got 2 eggs, side of toast, potatoes, ham (you can get sausage or bacon instead). I was very full.
They have a number of breakfast meals, most of them under $10.
I'd go back here for a casual brunch (or late breakfast). Or just for coffee.
They also have lunch and dinner items. To give you an example, they had a turkey dinner on for $11. Deal.
