Being Armenian you try and seek out places that are owned/operated/serve Armenian food and Arouch is one of those places. I come here often for a quick bite for lunch since its close to my work. They have, of course, Lahmajoun, Greek, Aleppo, Zahtar, and Anatolian (cheese) pizzas. I have tried all their offerings and they are all great. You can add toppings to any of your choices. My personal favorite is the spicy lahmajoun with a squirt of lemon. It just enhances the meal and in my opinion requires no extra toppings.
They also sell candy from Yerevan (Grand Candy). I would recommend trying a couple of pieces because its actually really good.
