Armed with crusty bread, generous heaps of pickled vegetables and jalapeño, and higher quality meats than you’ll find in other shops, Ba Le has all the classic options, plus about 20 others to keep banh mi fans sampling for years to come. Eel banh mi? Why not? Vietnamese meatball and egg? Most definitely. And with every sandwich priced at under $5, this might just be the best lunch deal in the Bay Area.
