I used to like the mussels at Convito Italiano in Wilmette - their online
menu says they have two options, basically one with a tomato wine sauce and one with parsley. I think I had the parsley-based one, nice acidity against the sweetness of the mussels.
LuLu's Dim Sum and then Sum has mussels as well, "steamed with a tamarind, chili, lemongrass & cilantro sauce" which didn't agree with me very much, but were interesting.
I haven't had either for quite some time, but there are two ideas.
