We came here a couple weeks ago (February 2015) for Mom's birthday. It used to be one of my…read morefavourite places to eat, but I haven't been here since maybe 2007-08.
Mom played it safe with garlic bread and a Margarita pizza, while I decided to go for bruschetta and an American pizza Romana, neither of which I'd tried. The bruschetta was delicious, and quite different to what I was expecting - the base was a standard garlic bread, topped with fresh tomato, onion, basil, olive oil and freshly-made pesto. I'm hit-and-miss with pesto, but this was wonderful. The pizza was similarly excellent - a generous helping of slightly sweet pepperoni on top of a delightfully thin, crispy base, with marinara sauce and plenty of mozzarella. I was so busy eating I forgot to photograph it. I didn't taste mom's food, but she definitely enjoyed it (though she always does).
We splurged on dessert - chocolate cake for mom, panna cotta for me - which I found reasonably good, though a little sweet for my tastes. That isn't a slur against the restaurant though - trying a new dessert is always risky for me, as I'm not particularly into sweets, and I should have gone with the lemon sorbet. The cake (which I tasted) was rich, moist and delicious.
Service was faultless, and I'm surprised that other Yelpers have had bad experiences. We were here on a Sunday at around 5pm, and it was reasonably busy, but Gerard, our waiter, was professional, efficient and friendly. The restaurant has also been beautifully redecorated since I was here last, and we found the ambiance both peaceful and welcoming. All in all it was one of the best meals we've had out in a while (and we eat out a fair amount).
Edited 25/06/2015 - I am delighted to see that Pizza Express now do a gluten-free pizza. As someone recently diagnosed with coeliac disease, finding pizza that I can eat is almost impossible, let alone finding one that tastes good. At this point they only offer gluten-free as a standard base (not a Romana), and they don't yet do gluten-free garlic bread, bruschetta or dough balls, but those things may come in time. The gluten-free pizza was very tasty, and I highly recommend it to anyone.
