I went to The Sister with my 2 kids and 2 friends from out of town on the weekend for brunch. One advantage of The Sister is that it is large so we didn't have to wait for a table. I had the hangover breakfast sandwich which was good and unique but very messy. The waitress said they didn't have a kids menu for breakfast (really is it that hard to print out a few kids menus?) but she said the kids could choose from pancakes, eggs or french toast. My kids had the kids pancake which pretty small and came with a side of potatoes. My kids liked the pancake and would have eaten more but didn't like the potatoes which are a bit spicy and an odd choice for kids (although I liked them). Again a kids menu would be nice since if I had known that the pancakes came with potatoes I would have asked for fruit or a sausage instead.
Our waitress was unfriendly and seemed annoyed and our food took at least 30 minutes to arrive. The place started to fill up while we were there and our waitress greeted new arrivals by barking "we have no tables" when one potential customer asked how long a wait there would be she said they should look around and figure it out for themselves. I doubt I will be back for brunch.
