Asia 21 is hit-and-miss, depending on some unknown combination factors including the time of day, number of people at your table, what you order, the weather, and/or the average height of all restaurant patrons last Tuesday.
Quite a few tasty items that make a hefty lunch at around $10. Vermicelli bowls are my favourite, with strong Vietnamese coffee. Servers seem to speak very little English, so the menu is conveniently numbered.
Unfortunately food rarely comes out together, making for awkward group lunches. Servers seem constantly rushed, but unable to do anything in a timely manner. If the restaurant is more than half-full, they resort to bringing random dishes from the kitchen to random tables until someone claims it.
Cash-only.
