I'll be coming for a visit to Seattle soon. I've never been to this part of the country before. I'll be staying in the downtown area. What passes (cost-wise) for low to moderately priced lunch and dinners? Any and all recs will be welcome. We have no food preferences...we're not picky eaters, and don't care about ambiance. Just looking for a good meal at a decent price. Want to avoid national chains.
