We made the mistake of coming back. Only reason we did come was for convenience. My wife and I ordered a sausage scramble, looks like the split one sausage patty for two plates, service was slow but it wasn't the waitress fault more of a staffing issue. The coffee was weak, not sure how you mess that up, but they did it. Earned a free meal with the stamps but I just going to throw that away we're never coming back. Such a shame this place use to be so good, not sure what happened?!
