Its a matter of taste - personally I still favour the Shahenshah but know that others don't like it, Raj is good but small for eating in if a big group, not been to hot house for ages. Not a great fan of Ruby's as I find the sauces a bit too tasteless and runny. The takeaway on Parliament Sq is okay - sorry can't recall the name.
Haven't been to Shahenshah for ages as previously disappointed but things can change. Tikka Cottage was similarly on our "off" list but recently appeared on Just Eat so tried it last weekend and had an excellent tasty (if a little sweet) experience.
If you're a Bengeo resident Raj Villa is porbabky as (in)convenient as Ginger and has some really good dishes and friendly (but sometimes very slow/inattentive) service - allow plenty of time to avoid getting impatient.
