We had 2 take-outs. The resturant was crowded at lunch. The two items were so good, we ordered them a second day. The first was Massaman Curry Lamb (can't find it in Philly) and Pad Thai.

We stumbled on it and was good dining experience. The food was amazing, perfectly spicy and tasty. The service was ok with hardly a crack of smile, but food was our priority which was good.

Originally home to rallies supporting the Union Army
in the Civil War, this grand square has become the
city's premier shopping and entertainment district
containing the largest number of upscale department
