I've wanted to try both La Sirenita and CInco de Mayo. I was worried that it might cater exclusively to the local hispanic population and as I don't speak Spanish, I was afraid I might make a fool of myself! ;-) Thanks for the feedback on them. I think I'll try them now!

I have been to Mi Pueblo and enjoyed it. I don't know that it's exceptionally authentic... but it's a good place for American Mexican, unlike Plaza Garibaldi further down on Ritchie. The inside of Mi Pueblo is very pleasant for a strip mall and the staff were nice, attentive, but not obnoxious.

Has anyone tried any of the taquerias or small mexican restaurants along Crain Hwy or Ritchie Hwy?
