Zhonghua Noodles
The very loud slamming of dough on the counter as they constantly make new noodles. Get the "oil spill" and/or cold Xi'an noodles (涼皮).
OSMO X MARUSAN
A bit too cool for a café -- with its disco ball and daytime DJ -- but the Japanese curry is damn fine.
Mollo Bakery Café
Take a barstool at the front window and look out onto Notre Dame with a tasty pastry and cortado.
Drogheria Fine
$5 gnocchi in tomato sauce. The price is nice but the sauce is a little too gelatinous for my taste.
