I love 550 pizzaria and have, for the most part, had a great experience ordering their pizzas. My favorite is the Ellen. To me, it is the best one and as a bonus it is vegan and lactose intolerant friendly.
My only bad experience with them was recently. I ordered online through a link I got from their website. I ordered 3 pizzas and it said it would arrive at 9pm, however the driver would call to notify the pizza was dropped off, since I had chosen a 'no-contact' option of delivery. The driver never called me to notify me the pizza had arrived, nor did they even ring the doorbell. We later found the pizza in our doorstep all cold and cover in insects including a roach! I am not sure who was at fault, but I was even more upset that I was not able to do anything about it since the delivery page did not let me leave a review or complaint.
So, I would say take out and dine in is safe. DO NOT HAVE YOUR PIZZA DELIVERED! And if you do, ask them to hand it to you and be on the lookout for it!
