Etiquette Question - You are invited to a 60th at a restaurant, do you expect to pay?

[HotI]

I must know different 'old' people to you guys. I reckon the ones i know would assume that dinner at a restaurant for a birthday would be pay for your own meal. That's how all the ones i have been to have worked. who has enough to pay for everyone's meal?

And for your MIL's party, i also don't think you have to say no gifts just because people are paying for their own meal.

Thanks so much everyone for your opinions

We think we might give a link to the restaurant's menu (if there is one) and mention the mains prices, hopefully that will make it obvious without sounding rude!
