They share a store with Subway and are located closer to the back of the store. During peak lunch hours on a weekday, there is most certainly a line-up because of all the workplaces nearby. There are many booth and normal seats near the front of the store, but most customers get their food to go. When I had a chicken shawarma for lunch, I found the garlic sauce far too overpowering and strong for my liking, although the price was definitely very reasonable for the portion.
Staff are very polite and speedy with getting everyone's orders and food ready quickly. Overall, would recommend for a quick, cheap lunch.
