Staying at Marriott on Mission in Financial District for a convention in May. Limited mobility, as in, CAN climb stairs but rather not, CAN stand but can't stand in long lines, CAN walk but only a few blocks, uncomfortable on bar stools. Diabetic, avoid bread, pasta, desserts. Like farm to table, seafood. Picky, ok, but there are so many interesting restaurants in SF thought maybe the Chow community could help me.
