the undisputably best gujarathi thali i've ever eaten in my life is still available and rocking at the thacker club, which has been recently refurbished to include an ac'd room. warning: its tough to get to, and EVERYONE will think you mean one of the thacker restaurants in churchgate or chowpatty. NO! its in the dadyseth agiary lane, which is itself BEHIND marine lines.
the second one is jimmy boys in fountain, which serves excellent parsi food. its not as soulful as the rippon club, but you'd need a member to take you that venerable intitution.
