Everyone talks about Borough Market in London but this underground food court nobody mentions. It's not just shopping — Locals actually eat in the basement and the variety is incredible.

My favorites: Lebanese place with better hummus than I had in Beirut, proper Italian deli with imported prosciutto, Japanese counter where the chef trained in Kyoto. Everything under €15, restaurant-level quality.

It's covered so perfect for rainy days, you can eat in the little park outside. Way more authentic than tourist brasseries around Saint-Germain charging €25 for basic pasta.

Line 4 to Saint-Germain-des-Prés, 2 blocks from station. Open every day except Sunday.
