Teasim, which is in between the Mall and the convention center, is a great spot for breakfast. The tea cured salmon is great. Otherwise, your list looks great. I would recommend looking into Ceiba. Although I haven't gotten over there yet, it has received rave reviews around here. Since you are in the mood for seafood I would check out the happy hour at Old Ebbit. I think it is only Mon.-Thurs. from 3-7 but they have great oyster and clam specials. Don't forget Julia's Kitchen at American History.
