Since Café Altro Paradiso opened in late February, Grub has maintained that its spacious, bright dining room would be at its most charming during the daytime hours. But, so far, co-owners Thomas Carter and Ignacio Mattos have been slow about rolling out lunch, only serving midday meals on the weekends. As of tomorrow, though, the restaurant will be open for lunch — that is, from noon to 3:30 — on Wednesdays, Thursdays, and Fridays. If you can get away from work, you should make a point to stop by, since the menu will feature the same straightforward, relaxed Italian food, and the atmosphere promises to be more laid-back as well. Plus, the room will be lovely.
