We used to live in Watauga and missed our great cheap lunch until we found Pearl. The service is quick and the food is good for the price. We can have lunch for two for under $12 (not including soda's or a tip).
The lunch special comes with your choice of soup (hot and sour, wonton, & egg drop), an egg roll, rice and an entre. Not all of their dishes are available for the lunch menu, but they still offer a good selection. The portions are generous, too.
Oh, and John Travolta ate there the summer of 2003! :)
