Went to this place for the first timeand the chef didn't disappoint us. Barra kabab was great, felt like the one you have in Karim's , Delhi. A little disappointed with the "Raan", it was a bit under-cooked but had the spices and flavors.
The biryani and the mutton curries were great. I would recommend that you have only the mutton dishes rather than going for chicken, the mutton gravies over shadow the chicken ones.
Over priced though, and a lot goes on taxes. I expect them to improve on the "Sikander Raan" next time.
