Once place I do seem to frequent a fair bit, is Bella Italia. Mainly as it is convenient and also they accept Tesco Clubcard deals. Yes it is a chain and they probably use some kind of step system for cooking, but compared to some traditional Italian places I have eaten it isn’t that bad.
One thing I seem to order from the menu a lot is the calamari.
They coat it in parmesan before deep frying it. Sometimes it can be overcooked (not how I like it) but generally they do get it right.
I also quite like the pasta and pizza at Bella Italia too.
