Brunch Union/Madison Sq. on/near Bdwy.
Planning to hike/photograph Broadway from Battery Park to the Harlem River, maybe on up as far as VanC Park if there's time. Before you ask: Yes, I must be nuts and no, it definitely is not my first trip to New York.
Anyway, I'm looking for a place on or within a block of Broadway between Union Square and Madison Square (or a few blocks further, if necessary) for a mid-morning break on the second day. An omelet or some blini or ? Mainly, someplace to have a little something to eat (preferably something special), rest my feet for a little while and use the -ahem- 'facilities'.
Are you planning to do this on the weekend? Finding "brunch" in the middle of the week is difficult. If you do this mid-week, depending on what time you take your break, places that do serve breakfast might be switching to their lunch menu.
One option is L'Express, the 24/7 French "bouchon," on the corner of Park Av. S. & 20th St. Not special, but decent enough. Breakfast is served until 11 a.m. However, there are omelets on the lunch menu. I've had a very good quiche there.
Punch restaurant on broadway around 20th might fit the bill. Food is quite good. I think the place opens for brunch on weekends at 11 am or lunch during week @1130. punchrestaurant.com
Danal on Fifth Avenue across from the Forbes building. We had brunch there recently. It's better than the Coffee Shop on Union Square where we sometimes end up. Another for Lucia's Markt rec. Though I liked their old location better.
