This one might be an ask too far for anyone to remember - not least because I don't remember seeing anyone else in there when we ate in there!
The place in question was an Indian restaurant we would go to lunchtimes from the mid-70s up to about 1980 and it was on Edgbaston St, opposite the Rag Market. It was notable for the "Businessmen's Lunches" we would go there for.
Three courses for under a quid. Fruit juice or soup starter (both tinned, I think), chicken or beef curry and rice (or prawn for a surcharge) and ice cream or tinned fruit for dessert. I seem to recall coffee being involved but I don't know if that was an extra. IIRC, when we first started going there for a lunchtime scoff it was 75p but eventually was 90p.
Stonking value even if it wasn't the best food you'd ever eat. If it hadn't have been decent, we wouldn't have gone back because gash food is gash whatever the price.
So, I can remember quite a bit about it except the name. Any chance anyone knows what it was called? Whatever it was, I'm pretty sure by 1990 it was gone.
