The chops are awesome, their Dry Meat can be deliciously sour. You can have a great feast just repeating rounds of starters - chops / masala fish / mutton balls / grilled paneer (even the most ardent carnivore will like these).
Book in advance, know it will be mayhem in there, bring your mates and some beers. You don't go there for a couples anniversary meal. You don't go there if you're expecting fine indian dining.
It will be packed, hot, really noisy, and depending on what floor you're on (and how near the grills you are), all your clothes may need drycleaning.
It's a great night out, and the reviews below complaining just don't get it. Long may Tayyabs reign.
