Are you enough of a hard-core gastronome to attend Chris Cosentino’s and Seamus Mullen’s back-to-back event dinners? Cosentinois the famous West Coast offal master whom you may remember from his appearances on Iron Chef. Cosentino is doing a signature “Head to Tail” dinner at the Astor Center on Tuesday, March 4, hosted by Michael Ruhlman. Expect lots of tripe, testa, candied cockscombs, and the like. That one will set you back $250. On March 5, Seamus Mullen is doing a Basque “Homage to Euskadi” dinner at Suba, featuring regional specialties like hake tongues; tortilla de bacalao with poached hen’s egg; salt-cod brandade, pimientos de padron; beans and pork belly; and so on, all paired with big Basque wines. That one is $110 and should be a little easier on the old G.I. system as well. But what other city could produce two such feasts back to back?
