Nandos if you don't already know is a South African chain that hit London and spread like Wild Fire
The reason being well the chicken is incredible. They grill it in Peri Peri sauce and you can get it from very mild to tongue scorching. I go with the hotter options most times but not the absolute hottest one they make.
Everything is always fresh, they have good sides, bottomless drinks, staff is very friendly, and they even have Portuguese nata for dessert. Overall I can't recommend Nandos high enough. They have drastically grown throughout London for good reason.
One tip I would give if you don't want to wait get out of the very touristy zones as they tend to have the longest wait lists.
PS: they also have a few in the Baltimore/ DC area and I really hope they expand their quest throughout the US read more
