Yes, I went all the way to Las Vegas to have pho when there's a shop on pretty much every corner in my neighborhood. About half the group wanted to try the pho and the other half wanted food from the coffee shop. We were told that if we put our order in at the coffee shop we could order from both menus.
I ordered pho ga. I noticed they had a Vietnamese sandwich on the menu too. I was pretty hungry, so I went in on that with a friend. The pho, as I expected was ok, nice broth, tender pieces of chicken etc. The sandwich was the stand out of the meal. The bread was crusty, the pork was smokey and flavorful. I would definitely get that again.
I will note that ordering from both menus slowed down the arrival of our food to the table. I heard something about coordinating both kitchens. So I wouldn't try this if you're in a hurry.
