I'm taking a visiting friend out to a low-key dinner this week and am hoping to stay in the U District or Wallingford areas (but am willing to go a bit further if needed). I am looking for a place that is casual and inexpensive ($10-15 or less for entrees). I know there must be plenty in the area but I'm blanking on a good place to take someone who's new to Seattle. Food that's unique to Seattle or the U Dist would be nice but by no means a requirement. The food is the most important factor, not the ambience or niceness of the place itself. Thanks in advance for any recs!
