Ann Arbor: Lena?
Went to Lena in December with my husband. We liked the atmosphere. The food...not so much. While I didn't love Cafe Habana, the food was good enough. I didn't think Lena was as good, and it seemed pricier.
Haven't been to Isalita yet. I don't like to go to restaurants when they first open. Rather give 'me time to work out the bugs.
My favorite place for Latin American food is Mtaz Taqueria and Panaderia. The place has zero atmosphere but that tacos are fantastic.
