Pho Rex is an excellent alternative to the Korean and Sushi restaurants that occupy the Koreatown and Annex area. I was a regular at this place back when I lived in the Annex.
I was in the area the other day and decided to stop by for some pho. The staff is still as friendly, and the food is still delicious. The pho, in my opinion, is the best in the neighbourhood. And If you're not in the mood for some Vietnamese cuisine, the Chow Mein noodles and Flat noodle dishes are also good.
The pricing at Pho Rex is very reasonable. $3.95 for kids size pho (which is their small) - you can't really beat that! They give good portions for what you pay.
If you're in the area and you want something different, Pho Rex is a great place to try.
