Have you been to Celestino Ristorante at 141 S. Lake Avenue?
It looks romantic. They've got this front patio and another one in the rear courtyard. They've sheltered the one out back with a little forest of potted plants, but the courtyard is surrounded by offices. I prefer the less corporate street atmosphere for a romantic dinner. (I'll meet you out back for a business lunch.)
There's a dining room indoors, and the website has a virtual tour, but I couldn't get it to play. I couldn't manage to download the menu, either.
Not having been to Celestino I resorted to Yelp reviews until Mr. Earl corrected me in the comments. I won't be recommending Yelp anymore. My commenters, however, recommend Celestino.
But I'd rather hear yours.
