Thank you @DanTheMan - had another recommendation for Mughli today at work so good to know that it’s a good standard. Think I’ll try there. I’m based at the hospital so curry mile is much more convenient than town for me.
Very similar story to what you’re describing in Ladypool road in Brum. The Balti Triangle is definitely less Balti and more shisha and grill. Good eats there still, but harder to find a Balti house.
