The example on the left comes from the Christian Science area along Mass Ave. You can't argue with its simplicity. The example on the right comes from the side of the newly renovated Taberna de Haro restaurant in Brookline. I haven't been, but I like its style. The (huge) homage to Singer Sargent's El Jaleo (on display at the Isabella Stewart Gardner Museum, fittingly) is very appropriate to both the region and cuisine.
Til next time!
