A friend and I lunch monthly at the Bristol Lounge, more for the comfort than for the food. (The food is fine, but we go because it's a great place for a leisurely lunch.) Next week it would be more convenient if we could find a place for a leisurely lunch in or near Belmont or Watertown. She'll be coming from Watertown Square and heading to West Newton after lunch. I will be coming from Cambridge and heading to Belmont Center after lunch. So really anything in the corridor from Fresh Pond to Watertown, including Belmont and Arlington, probably would be convenient. Any suggestions?
