MushroomMike,
in all honesty i am sure more than the adil and kyber are top notch in the triangle - having said that the adil is well worth a visit. if we can talk bengali bob into arranging another visit then i'd like to compare how far i've got to their offering (now i know more gained from this post).
the balti house product is very different from anything classed as a balti in BIR's. i've sampled the west side of england and not come across anything close. i can only describe the difference as a very clear spiced dish, that has a tad harshness, lots of garlic, tomato, coriander. my previous fav has always been the plain chicken and mushroom. i'm now sold on the meat version.
like all places nothing is perfect - the grill was a tad stingy and the naan not quite as good as best (i've had them slightly more crispy again might not suit everyone) yet the size of it easily made up. it's a "cafe" experience too which does not suit all ie no table cloth
i'm well pleased i went and if a bit closer would be dropping in regularly. it has what i know as curry pedigree.
