When I spoke with Lynn earlier this week he said they're opening for the season on the 9th. But tonight at the YumaDunerDinner he said they would be opening next thursday. Not sure if he was off tonight or the last time I talked to him....so it may be a good idea to call ahead if you're expecting them to be open
I have a number for them but I'm not sure if it's public so let me check before I post it.
Not sure what their hours are....never seem to be open late enough for me but I'm a latenik so not many places are open late enough for me

I seem to recall they close at 10PM or something like that though. No clue how early they open but it's earlier than I wake up
