It really is as good as it gets. I've been there 4 to 5 times and have tried a lot of dishes. Bangers & Mash was ok, but I really loved the Chicken Tikka Masala. Soups are amazing, and come with slices of bread & butter. It's really heavy. Oven chips is the best side I've had over there. Deserts are amazing as well. They have lot of drinks but I tend to go with what the staff recommends. I've never been disappointed.
Tip : It might look a bit shady, but don't let that deter you. Take the leap of faith and trust me, you will not be disappointed.
