Luckily I was out in London to see a musical, and planned to have dinner before the show started. What was fortunate was the distance from the theatre to On The Bab, it's a very short walk from Covent Garden underground station.
We arrived to the restaurant, which looks like it also caters for takeaway and for Deliveroo so you could get it at work if you're working in London. We were seated almost immediately, which was lucky as I believe if you arrive around 6:30pm or longer then prepare to wait in a queue. The interior was exceptionally cramped, not as cramped as Misato.
Staff appeared to be attentive when we walked in, but when we were ready to order I must've been waiting for a good 10mins before someone noticed we haven't ordered anything.
We ordered one dish each; Kimchi Bokeum Bab, Beef Bibimbap, and then the fried chicken (Yangyum chicken). There are 3 to 4 'sizes' of the chicken which is basically portion sizes which equated to X amount of chicken, and to share it was good just to go for Medium. Though just be aware it's not X amount of chicken wings or thighs or anything, they don't do it the way Colonel Sanders, it's X amount of chicken PIECES. Yes, you still get wings and other conventional cuts, but it's not always going to be all of that, you'll get nuggets and other stuff. Don't be sad though, because it tastes brilliant! You also get a choice of 4 different sauces that get drizzled on before serving. We chose the sweet spicy, but I'm told by my friend that we could've just had a mix of all 4.
