I walked over to Firehouse Subs for a salad today and learned the handy place in the Block 2 development will be closing Saturday and its owners moving to Florida. Coming in its place I was told: Crush, a wine and cheese bar that will open at 4 p.m. and cater to the evening crowd. Our Insider column this week mentions another change in the neighborhood, a “fusion” sushi restaurant, Wasabi, in the former San Francisco Bread space at Markham and Main.
