Your reports/reviews are of a real interest to me. I have had similar results from the 'recommended' local BIR's. I'm never quite sure if it's a decline in the quality of the food or my tastebuds expecting more, especially since I have learned how to cook a decent curry. Today I had a curry day, made a new batch of base, fresh mix & GM powders, pre-cooked chicken, GG paste, and so on. Also, I knocked up a 'takeaway' I promised my Son and his wife, he told me it was the best he had ever had! This might well be down to my cooking but more likely down to the deterioration of the aforementioned BIR's. I think if it wasn't for CRO and the folks that have moved on I would still be eating bland curries.
Not sure if I have made a relevant point but there does seem to be a recurring theme on declining BIR's.
Cheers,
Ken
