I would encourage you to consider significant deviations from your route. On Sunday mornings, there's very little traffic, so it won't take all that much longer if you decide to try a brunch elsewhere on the North/Northwest Side. Even going to downtown won't take all that long (the expressway would make a return home quicker), and would be worthwhile if you enjoy different and creative brunches. Of course, if there are places along your route, it's even better; I just don't know of any. Hopefully others here do.
For me, the basic conundrum for Sunday brunch is whether or not to go to a restaurant that accepts reservations. You can avoid a lengthy wait to be seated by doing so, but that restricts you from going to the restaurants that specialize in breakfast/brunch, most of which do not accept reservations. For example, of the three places you mention,
M. Henry (as well as
Uncommon Ground) does not accept reservations, and waits to be seated are typically 30-60 minutes on Sundays between 9:30 and 12:30. I don't know whether the waits are any less at its new sister restaurant,
M. Henrietta, slightly to the northeast.
Vincent accepts phone reservations, and
Big Jones accepts them over the phone and on Opentable.
I love our breakfast/brunch specialty restaurants, for their savory dishes as well as their sweeter ones. My favorites on the North/Northwest Side include
M. Henry,
Marmalade (on Montrose),
Jam (recently moved to Logan Square),
Lula (also in Logan Square), and
Southport Grocery. I also love
Walker Brothers, to the north in Wilmette and Glenview. But you're going to encounter the same problem with waits to be seated on all of these places at prime times on Sunday mornings. I also like
Kappy's in Morton Grove a lot; I haven't been there on a Sunday morning so I don't know what the waits are like there. Check out the menus on their websites to get an idea of what they offer for breakfast/brunch.
