My folks are visiting next week and I'd like to take them for a walk around the Venice canals and then for a nice lunch somewhere on Abbott Kinney. They have good taste, but will probably want a really nice sandwich, soup, or salad rather than a heavy meal. Also, they aren't cheapskates, but they won't let me pay and they live on a fixed income, so I'd rather something reasonably priced.
Bonus points for sitting outside.
Abbott Kinney is better, since I think they'll be charmed there, but Main Street in Venice is a great second option.
