I think this restaurant on Newbury Street used to be Sol Azteca (10 years ago when I lived in Boston). I never really liked the ambience then and I don't really like it now - just too dark (it's downstairs in the basement). The tapas was good, but not anything special and there didn't really seem to be an signature dishs (just a lot of "generic tapas choices" - things I've had lots of other places that are standard spanish fare. The meal was reasonably priced and if you are in Back Bay and MUST eat Tapas, this is a good choice. Otherwise, keep looking.
