I have been going to Ajwa for the past 10yrs. Cheap, and best. But not the cleanest. I like Biryani and tandoor items and also the kababs. VFM.
Service is typical old city. No washroom. Can take family on first floor though not recommended.
Sheek kabab in the evening is the best u can find in the old city. But still not comparable to ones in Kolkata.
Anyways if u don’t have much in pocket and want to fill ur tummy, head straight away. Ofcourse u have to ignore the cons.
