Been here before, but just had lunch here again and it was great. Contrary to what it says, they do take resos if you call (asked them when I was paying). And if you plan on coming here for lunch on a weekday, you should get a reservation unless you come here early or late. We got here 5 after noon and it was already packed, luckily there were two tables about to leave.
Ordered #67 which is great here. It is banh hoi (vermicelli sheets with green onion oil) with lettuce, carrots, cucumber, basil. For meats they provide the sugarcane shrimp, sausage and beef in betel leaf (the best). They provide rice paper on the side and you essentially roll your own salad rolls with whatever you like. For $16 it is a lot of food and extremely delicious. I am not Vietnamese but it is comparable to ones home-cooked ones and ones I have had at Spring Vietnamese Cuisine.
Ask for the bill at the counter and pay at the same time. The server was nice enough to let us know that our food was arriving (meats were still being BBQ'd). I would also recommend the Bun bowls here but can't comment on the Pho (friend said it was OK, perhaps a bit sweet).
