Pho Hoa is a chain, and I have been to several other locations. Recently, we went to this one for first time, simply because of a coupon we had.
When we inquired about the coupon, the waitress, who didn't speak English well, did not do a good job of explaining.
Food is typical of Pho Hoa, which is pretty good, with a good amount of meat.
After we finished, and tried to apply the coupon to our bill, we were told that we didn't spend enough to use it. After arguing with them for a while, we ended up buying an extra smoothie just to meet the requirements of the coupon. It would have helped if the waitress had explained the coupon correctly.
The table next to us had the same coupon, and they too misunderstood the terms.
I don't know if the words in the coupon were poorly stated intentionally or not, but it's never good when the waitress couldn't explain it either, and you are surprised at check out time.
