What's the difference between butter chicken and tomato water with chicken in it? Nothing if you order it from Copper Chimney.
I've eaten here for about 18 months and watched it go from mediocre to utterly disgusting over this time. They have switched owners 3 times and none of them are able to operate it.
On to the food, I wouldn't bother ordering any of it. This butter chicken I am eating right now it awful. I don't think there is any butter whatsoever. Granted this is no Mango Shiva, but you would think an Indian couple would be able to put out something that resembles butter chicken. It seriously tastes like tomato water. I can't even smell curry in it. Their mixed vegetables are gross and I'm not brave enough to try anything else they have on their menu, based on what I have on my plate now.
Don't waste your time. Let this place sink so they can replace it with a restaurant that is able to serve cuisine.
