My thoughts about the "new" Mission Diner are pretty much the same as the person who reviewed it in early February. Ate breakfast there for the first time today. Service was fine, prices were fine, portions were fine, but nothing was outstanding. I'm celiac so a lot of the menu items weren't an option for me, and as a result, I didn't look over the menu too closely....I'm sure others could order a more interesting breakfast than my standard 2 eggs with choice of meat, and hashbrowns. They gave me a good serving of nice fresh fruit instead of toast, which was very much appreciated, but otherwise, the breakfast was pretty unremarkable. The scrambled eggs weren't too greasy, which was nice, but the hashbrowns were overly so. My sausage was butterflied, so I don't think I got a whole sausage, but I appreciate that they use Spolumbo's because they're good quality and gluten-free.
Would I go back? Yeah, if I'm in the neighbourhood and craving a big breakfast, but I don't expect I'll go out of my way to eat there.
