UK LADIES!!

Hi! 
I'm going out for a meal for my birthday tonight. I've looked at the menu and the only things I fancy I can't have or unsure whether I can have.
Is it safe to have lasagne, the only reason I ask is it says bechamel sauce in it (this is the description: Layers of Egg Pasta with Mozzarella, Bolognese, Parmesan, Béchamel & Tomato Sauce). And I wasn't sure if that was ok to have?
Secondly, if I chose steak is it safe if well done?
Stupid questions I know, I just don't want to put my baby at risk at all,
Thank you for any answers xx
