A downtown grocery store is needed and will eventually get built as the number of people living downtown continues to soar. Also these downtown dwellers are far more likely to be car-less so going to the burbs is often not optional.

It certainly doesn't need a big one but more the size of a small/medium sized Metro. Of course the pushback will not be from the City or downtowners but rather from the merchants in Covent Garden Market who will think this will eat into their shopping base. I personally don't think that is an issue as the Market is more of a destination than a grocery store. No one goes to the Market to save money on their groceries but rather due to the shopping and entertainment niche it fills.
