Need a nice moderately priced spot for a dinner 7-10 guests, ages from 60s to 90. Need a quieter room. Most are staying at the Hotel Monaco, Wabash just north of Randolph and a short cab distance is preferred. While I don't normally favor hotel restaurants, if the South Water Kitchen is good it would make my life simpler. Oh, and there may be a vegetarian/kosher person or two in the crowd. Any thoughts?
