The risk from unpasteurised cheese is a listeria infection which can affect the baby.
No normal restaurant (by normal I mean not Gordon Ramsey's or similar) is going to serve unpasteurised cheese and especially not in a cheesecake, so don't worry. They just wouldn't risk giving one of their customers (pregnant or not) listeria because the repercussions from Environmental Health would be really bad news for the business.
The risk from uncooked egg is salmonella which will make you ill but will not harm the baby, however an associated high temperature might. It is virtually impossible to catch salmonella from UK produced eggs because they are all treated.
Manufactured products (marzipan, mayonnaise etc...) will not contain raw egg because it cannot be preserved for long enough for the product to actually get to the shelves of the shops.
I wish there was more explanation about what you should and shouldn't eat in pregnancy instead of just a list of don'ts because it terrifies pregnant women unnecessarily.
Stay calm, rational and realistic. When was the last time you or someone you know had listeria or salmonella? If you've eaten something on the don't list and it hasn't made you ill there is no risk to your baby and you can stop worrying.
Sorry for the rant but the lack of information about this really annoys me!
