If you need proof that To Chau is highly regarded for its authentic pho (Vietnamese beef noodle soup), just check the lines that form in front every morning of the week. It's said that the broth is the key, and it won't break the bank for you to find out, as the average check is less than $10. The restaurant is open only until 2:30 pm, but you may be turned away if the food runs out earlier. Reservations not accepted. No credit cards. No dinner.
