Met a couple of friends there on Saturday, the food was ok. The real problem was, the restaurant was very hot & stuffy inside. My friend asked if the AC was turned on, if it was could they lower the temperature? The waiter, who was very nice said, he did speak to his manager and she will not lower the temperature of the AC. A short while later we paid for our checked, walked outside...Did you know it was cooler outside of the restaurant then inside, in the month of August in Vegas...That should tell you how hot it was in that restaurant.
To summarize: Food, just ok. Restaurant: very hot inside. Winter months would be a better time to visit Pho Thanh Huong!
