I love love, love, love China Go XP! And this specific one located on 13th Street. First of all, the staff are always friendly and very helpful. When the owner is there, She is amazing as well.
The portion sizes are huge, seriously enough food for two people when you order any one entree item with rice or noodles. And here's the big one, they have an entire menu for Celiac/ gluten-free people! The food is delicious and I have never had a reaction in the 4 years that I have been coming here. The only reason why I gave it four stars instead of five for atmosphere is because the tables don't seem to get clean when we come to visit. I understand that in today's climate not every establishment can have enough workers, so something's got to give. But if there's one thing I could change about this place, it would be that the table/dining area gets cleaned up more often.
