I’d suggest something a bit leftfield and heading to Southall for some Sri Lankan food instead. Similar to Indian, minus the cream.
+1 (although real Indian food doesn’t use cream)
I’d head over to Southall Broadway for some real South West Asian food. You’ll find more authentic North Indian, Sri Lankan and Pakistani food.
The North Indian and Pakistani food may have similar names to curry places you’ve eaten at before but should be made to a more authentic recipe.
The South Indian or Sri Lankan food will be very different from a curry. I’d recommend trying out a Dosa if you haven’t had one before.
I can’t recommend any specific places as its been ages since I’ve been to Southall, I mostly eat Indian food around Harrow and Wembley which might be a bit too North for you?
