I've only seen this at Wagamama, as you've described, and at Outback Steakhouse at Niagara Falls (before it closed). I think from a DCC perspective I prefer this because you have control of the terminal throughout the transaction. With the way it works in these scenarios, you'd have more control to abort the transaction if you get a hint of forced DCC.
