Il Corso is the relatively new sister-ship to the charming Tiramisu, which is only a few blocks away, but here the smallness and dark intimacy of the older restaurant gives way to lightness and quite a bit more space. The food is up-scale Sicilian-Italian with well-prepared seafood, veal and pasta dishes; their branzino (sea bass) is a regular specialty, the grilled and breaded swordfish (pesce spada) is a worthy treatment of that very Sicilian dish, and the linguini neri allo scoglio (pasta blackened by squid ink) is only occasionally found in Italian-American restaurants. Il Corso is not for the faint of wallet (those who don't own Amazon stock) and one would have to practice serious self-denial to keep the cost below fifty dollars per person (tax and tip included). However, it is not the price that loses a star for me, but, unlike Tiramisu and the nifty Mama Gina just down the elegant El Paseo where the waiters are both highly professional and mostly Italian and where my query concerning "pesce spada" is met with a courteous answer in Italian, at Il Corso the servers are most accomodating and desirous to be helpful, but they are not the real thing. Not enough to keep me away, but I prefer the sister-ship. Eh, Ciao.
