Sorry you had a bad experience at Red Chili, but I’ve never had one in my visits. Nor had any inconsistencies with their food. Service can be slow, especially at busy times, typical of a small staff.
Tawakal is also very good, though I haven’t been since they moved to Woodland Hills. I actually prefer their nihari, which I greatly appreciated when I had a cold, but I digress. The downside is Tawakal has a much smaller menu, even though they do have kata kata! Red Chili’s owner is actually from Karachi.
Both are no frills, very basic restaurants. Nothing fancy about them - even quite the opposite, They just serve good national cuisines to local communities.
