I received a menu flyer on my doorknob last week and decided to give Zella's a try. I called and spoke with a gruff gentleman who took my order. I purchased the large, one-topping (pepperoni was my choice) pizza with garlic parmesan breadsticks and a 2-liter coke. The total was 10.83 (carryout).
PROS: Pizza was worth $5--not overly greasy and enough toppings. They sell Coke products--I hate Pepsi. 15 minute turnaround time, so not a long wait.
CONS: Breadsticks were only "ok"--will not purchase again. Also, the guy at the counter was seriously lacking in customer service skills. I stood there (no other customers in lobby) directly in front of him for like three minutes while he was writing something down before he even acknowledged me. Not a big deal, because it's just a pizza pickup, but I knocked off one star for that. Not a 5 star experience but I will definitely be back.
TL; DR: Get the $5 pizza, skip the breadsticks, Coke products if thirsty, short wait time for carryout, and lackluster customer service
