Several people have asked about Seoul Plaza at Security Square Mall, but no first hand reports. Seoul Plaza is a group of Asian-owned or related businesses that are in an old department store.
On the upstairs level, there is a small food court with four stalls and two restaurants. Of the four stalls, only one place (two stalls wide)was open. It had several Korean dishes on the menu. The two remaining stalls had names up, but the spaces weren't finished yet. One looked like it might be for sushi.
The bigger restaurant is called Miss Pho and specializes in Vietnamese pho. The small bowl, which is pretty big, is $5.45 and the large bowl is $6.45. The pho noodles come with any combination of 6 different meats from eye round to tripe. The menu lists 17 different "Chef's Recommendations," but presumably you could mix and match any combination you wanted.
On the side, the pho came with bean sprouts, basil, cilantro, jalepenos and lime in pretty generous portions.
Other than pho, the only other items on the menu were spring rolls and fried spring rolls. The spring rolls were two for $2.50 and were large cold rolls with an excellent rice paper wrapper and were stuffed with noodles, shrimp, pork, and avacado. Avacado is not a traditional spring roll filling.
The fried rolls were 7 for $2.75 and were very small, greasy and look like they may have been frozen pre-wrapped ones like the Asian grocery stores sell.
The place did not have other Vietnamese dishes like banh mi or grilled meats with noodles, and no rice dishes whatsoever. Like a lot of places that only serve pho, the broth tasted richer and fresher than restaurants with a wider menu.
The "authenticity" of the place is suspect because the menu is in English, Korean, and Vietnamese in that order, and the wait staff did not speak Vietnamese. Pho seems to be very popular with Koreans and other than avacado in the spring roll everything was very traditionally Vietnamese. Overall a very good place for inexpensive rich pho.
