I always looked at the quality of the restaurant and picked food accordingly e.g. hot food rather than cold. I did eat seafood throughout last pregnancy and have in this one. I think I avoided oysters but did eat prawns, mussels and most types of fish - I am sure at a good seafood restaurant (is it somewhere you know has a good reputation?) there will be plenty of things to choose from.

Really the only thing I restrict myself is food from lunch platters in meetings at work (because often have been standing about ages and you can never be sure when was prepared or who has had their hands on them) and sushi from sushi stores (I have eaten it when made fresh by friends though).
