I've not had the mild bowl ,Same dish but different BIR Chicken tikka cooked with olive oil, yoghurt, fresh garlic & naga chilli
Very hot,Mild Bowl ,Chicken tikka cooked with olive oil, yoghurt, garlic & fresh cream
Mild

My local is in suffolk,Its called Bay of Bengal,,It does look similar to a bhuna,I'll get a pic when i order again,Heat wise it's very hot ,Not phall heat i don't think although i've never had one  but certainly hotter than a madras or vindaloo

Found this at my local BIR this is the description
Cooked bhuna style with yoghurt & chefs special hot sauce made from gosht chilli peppers & green chilli peppers
Anyone got anything close???
My favourite BIR purchased dish at the moment
