Update: I wanted to increase my rating because this place does freshly fry their Chinese donut sticks AND makes their own rice noodle dishes. And I can certainly appreciate that when both these items don't taste as fresh elsewhere!
YES, it does tend to get busy on the weekends, so just come early. Line moves efficiently enough though.
Even though it's a busy place, I've never found servers rude or pushy. Food arrives promptly after ordering.
Note: At least half the patrons in-line are waiting for takeout orders. So don't be discouraged by the amount of people out in front. Just take your # and listen to how many people are ahead of you!
