Normally when I go to a sushi bar, I ask for omakase service and unless they have a pre-fixed menu, they would just give me pieces and tally up what was given to generate the bill.

For my recent visit, I somehow unlocked an open sushi bar because the chef suddenly told me that it's now my choice and he would make whatever I ordered and not include it in the tally. That is, these pieces were free! He would even give me the end pieces of blocks of fish after fulfilling other orders!

Now I just need to remember this cheat code for next time...
