I have had Chinese food in many places - Peking Garden is certainly one of the very best of them.
I love spicy food. That's why the spicy chicken from their special menu is my all time favorite. If you are into spicy food, you'll love it!
To balance the heat of the spicy chicken, you can have the gan-shao shrimp. It's a sweet and sour dish and will certainly complement the fiery-hot spicy chicken.
Other recommendations include mongolian beef, eggplant in garlic sauce, and fish-in-a-plate with spicy sauce.
In ethnic restaurants I try to avoid dishes commonly found in fast food restaurants (orange chicken, general tso's chicken in a chinese restaurant for example). So, if you want to try something different Peking Garden is a great place - the owner, although not very fluent in English, tries her best to accommodate your needs.
