Im a really pleased i live on the same road as karahi. we get takeaways. you pay slightly more than average for the food, but it is well worth it, the quality and the flavours are unlike any other indian food i have eaten before. highly reccomend the honey bbq wings or chatpata. the tikka masala's are awesome aswell as are the jalfrezi's.
havent eaten in the restaurant yet but its really well thought out and looks cool. take away wise they are quick and reliable, although it can be frustrating ordering as everytime they have to ask for your number, full name and postcode even though we order every week. also you get free bottle of coke for over 20 quid but it would be good to have free popadums or dips, as they are overpriced.
all in all highly recommend you try the food. for a cheaper option curry spice is a good little takeaway a bit further down the road
