I thought I'd give Asda a try, and not rush to judgement on it until it's had time to settle in. But I have to say I'm a bit disappointed. Yes the prices are noticeably lower than the Co-op prices were, so that's a big plus. And there are some nice bottled beers at sensible prices.
But the poor bread selection, the limited stock of fish, and above all, the lack of a deli counter, are real minuses. Without a deli counter the only sort of ham and other cooked meat you can get is that slimy stuff in thin slices that comes in plastic packaging and tastes of nothing!
But it seems to be quite popular - it often feels crowded, although that may be because they have tried to squeeze in more shelving, so the aisles are narrower. I still prefer Morrisons.
