The up to $20 credit is consistent with the concept of the Kimpton "raid the bar" credit which is $10 in most US locations, $15 in NYC, and maybe different internationally, I don't remember. Also note that some of the smaller Kimptons don't really have a restaurant.
But as a current Inner Circle, it does seem like they are aiming for a rationalization of the Kimpton, Regent, and Intercontinental status programs as they know that Spire just means a points bonus and not any real per-stay benefits.
