Other than Saigon Sandwich, which I maintain is the default Vietnamese sandwich shop most people new to them will like best (they most resemble American sandwiches in size and filling)
There’s also:
- Hello Sandwich
- Bo & Beurre
- L&G
- Mong Thu
- Sing Sing
- Tu Kim
- Vietnam House
Mong Thu is just an overall great little cafe and everything is good there
