I guess a 3.75 would be more justifiable for me, but that may be a little too technical. I think it's great that there's a pho place on this side of the strip. Technically, the pho shop is now joint to the Coffee Shop at TI so you can order eggs and bacon with your pho too.
I've been here a few times already at various hours of the day. If you can get here at an off hour, service would be much better. Most recently, we came here on Christmas Eve for lunch and although we got seated early, we had to wait about 10 minutes for our server to finally come around for the first time and ask if we wanted anything to drink. The food came another 20 minutes after that.
The food itself is a obviously higher-priced because of the location. For what you're paying I do think you're getting a pretty good sized portion and if you're not super hungry you can probably even share a bowl or a plate with a friend or family member. Don't expect the best and most authentic Vietnamese food in the world, but it's actually pretty good. Enough to satiate the asian food crave, if that's what you want. The #14 chicken with rice is actually pretty good as well.
