Stopped by twice during our London trip, as I'm a big fan of spicy food.
On my first visit, I ordered a "Hot" Single Slider and wow it was delicious and to my surprise really really spicy. It brought tears to my eyes and my nose was running; but in the best way possible. It was awesome.
On my second visit, I ordered another "Hot" Single Slider and to my disappointment, it wasn't spicy at all. Just well seasoned (but still a very good slider).
Not sure if the first or second one had the wrong seasoning to really be able to judge the "Heat" levels. That's my only complaint right now.
The staff was super polite and funny, the tables were cleaned frequently times and there was plenty of seating.
Definitely worth a visit if you like chicken and spicy food, but it's just hard to reccommend a "Heat" level after my mixed experience.
