In davis square, I see many restaurants that look like they could be a good place for a quick lunch: some place casual where I can get a simple lunch alone for less than 10 dollars or so. Are the sandwiches (or whatever) at any of these better than the rest? I'm thinking about Someday Cafe, Mike's, Joshua Grille, Natural's, Diesel, Blue Shirt Cafe,... I'm sure at least some of those are fancier or more expensive than I'm looking for.
So, which restaurants should I try, and which dishes (or sorts of dishes) are best? (My list up there is by no means complete... I'm just trying to give an idea for the type of restaurant I'm thinking of, as opposed to Wing Works or Diva, say.)
