Diner Dash makes the transition well from PC to console. The only real sticking point is that Flo is a bit floaty to control which makes it especially difficult to select the right group of customers to seat at a table. And if you have multiple tables open, there doesn't really seem to be a rhyme or reason as to where pressing a direction on the d-pad will take them.
It seems like a small complaint, but when tasks are piling up and help is nowhere to be found, it makes for some unneeded frustration. The hot keys help with other tasks, and the expanded campaign from the PC versions is welcomed. If you played and liked it as a Flash game then you'll enjoy Diner Dash on XBLA.
