We'll be visiting SF for just a few days and, by all accounts, Dottie's is the place for our Saturday morning breakfast. It also happens to be conveniently located in terms of our plans that day. I noticed in another thread that the lines are, not surprisingly, long on the weekends. My query is simple: what time do we need to get there to avoid a wait of more than 5 or 10 minutes? I see that they open at 7:30. Is there already a line at that hour? Or are we safe if we show up at, say, 8:30? Thanks!
