Amid the pizza shops and art galleries, Little Italy has a hidden gem: an authentic tea house. With its afghan-covered couches and tie-dyed curtains, Algebra feels like your best friend's living room -- provided your friend is a hippie artist with a board-game collection dating back to 1973. The shop's 20 flavors of tea and its exotic Middle Eastern coffees are served in sculptured cups. There's free wireless internet as well as mellow music and a stack of games, including Parcheesi, Monopoly, and Scrabble. And if you solve the daily math problem on the chalkboard menu, you can win a free cup of tea.
