I came here with my friend on a cold Saturday night. Soup sounded really good with temperatures below freezing outside. They have a big menu with lots of appetizers, rice plates, noodles, and of course pho! I decided on the vegetarian tofu soup and it was delicious. I ordered a large, thinking that it was only a couple of dollars more than the small, so why not? The bowl I received was about the size of a large mixing bowl. It probably could have fed four people. Pho OK definitely doesn't mess around with portion size! I had several meals out of this one bowl of soup. The staff was very nice as well, and the restaurant is cozy. I will be back but will most likely order a small next time.
