TeaHouse noodles is a difficult place to review. On one hand, they have some very tasty and healthy combinations, however you can quite easily stray into no-mans-land with some of the combinations available on the menu. Don't be afraid to ask for a recommendation on what's popular if you have not been here before. If you're new to TeaHouse, you can't go wrong with one of the premade options such as the pad thai, freakin' chicken or Asian chicken chili over rice. These will help introduce you to the sauces and give you an idea on how to build your own bowl to achieve a good flavor profile.
I usually ask for easy sauce on any of the dishes, as they can be a little overwhelming with sauces (though they are very good). It can be on the messier side to eat, especially over noodles as they have a tendency to fling sauce every which way.
Overall, TeaHouse is a good place for a quick, healthy meal and great option for vegetarians.
