I think they're good but it's a shame they are all chains. Las Iguanas is good but the service is shocking slow (given that lots of their cutomers are trying to have a quick bite prior to a concert). Le Pain Quotidien is massively expensive and not as good as Paul IMO.
There will be more eating places opening soon.
Giraffe is great for accommodating small kids and the food is surprisingly good. You get a free balloon too (but you may need to acquire a kid first)! Strada was excellent too so my preconceptions about chains are being eroded a tad.
