Currys

*Curries unless you’re talking about the electronics retailer

those Indian takeaways… tandori?

If you’re just referring to the restaurants, I’d just call one of those restaurants and Indian (as in the cuisine) or maybe a curry house. Tandoori, Balti, etc. all relate to styles of cooking and may be used in restaurant names, but if I was referring to restaurants that serve Indian style curries in general, I would just call it an Indian.
