There's also a Five Guys in the Chinatown area, which only has a handle of Chinese restaurants left since most have bolted for the 'burbs after real estate prices in the area skyrocketed. One of my lunch favorites was Chinatown Express for its lai mein noodle soup. It's the place with the guy making noodles in the front window. Next door is a hole-in-the-wall Vietnamese place that does a good business on banh mi sandwiches.
