Hi, welcome to SQ!

I would most certainly peruse the BTC menu and preorder. The selection is quite varied so you'll most likely find something that you'll like.

And, if there's something in the onboard menu that you like, you can usually change to that (subject to availability).

I've posted this before but I've taken a few shots and written up a little on some of the foods that I've had in business class BTC over in my blog (click here)
