LN Gar: One of the place where you want to taste really good coffee, love their flat white. I highly recommend for breakfast or just grab a sweet to take away.
Yilin Z: Bread, cake. There's always a line during lunch hour. On Sunday morning there's a "fast lane" on the side just for the "pains" and the "viennoiseries".
Aldo Junior: Best baguette in paris (as they say). Good space. You can eat on the tables outside or pick up. Sandwich baguette costs 3,8€. Baguette is 1,15€ (The big one). Macarrons are great!
