I came to Nando's with two coworkers during lunchtime on a weekday. You go up to the counter to order, but servers assist you with seating and bring your meal to the table. It's a very casual setting, and quite fast.
I really, really like the chicken (not dry at all) and the spicy rice. I am also a big fan of the sweet potatoes. They have a variety of sauces (different spice levels) which are good.
