Thai Chili is right behind my house so I've eaten here several times and tried most of the curries and found them all to be very good! Some of the combinations are a little odd (yellow curry beef?) but I think they're just trying to cater to a broad audience.
I'm quite certain that they're using a store-bought paste but that's not a knock on them as many places do not make their own pastes. Very reasonable prices as well!
