This as become my new favourite place when I want something cheap and fast. The price of their sandwiches is ridiculous. For $3 I can have a full meal. The sandwiches are tasty, they have lots of different meats to choose from that are not available at other viet sub places like Banh Mi Boys - e.g. cured pork, pork skin, lemongrass sausages. You can also add pate to a sub to make it even more delicious.
Whenever I go shopping at Chinatown I always pick up a sub for dinner and another one for lunch the next day. You can probably keep the subs in the fridge for up to a day.
