No concerns whatsoever about cross contamination. Very little gluten is used here and everything is very clearly marked on the menu, with accommodating and friendly staff.
That said, do not skip this restaurant. This is the best food to have ever graced my taste buds. The dishes are a creative blend of different cuisines and transport you to another world when you taste them. The textures and flavors are outstanding. This isn't just a meal, it's a work of art and a culinary experience.
Eat here. It's the best restaurant in Philadelphia for sure, possibly anywhere.
