One lunch and one dinner, staying in Lake Union

[Miri1]

I'm in Seattle, Lake Union, for one day, tomorrow. I'm looking for either a vegetarian/ vegan place or fish, but not shellfish. If it's fish, I prefer simpler preparations like grilled or broiled over seared. Better still if there are baked potatoes alongside. And please, casual is a must. I'm willing to pay a little extra, willing to travel a bit, if the food is really worthwhile. Suggestions please!
