Looking for a good quick hitter food location near Paddington Station

Any reason for going to Paddington? Other routes to Pimlico would be easier and quicker.

Or Victoria Station instead of Paddington?

For clarity are you wanting somewhere near Paddington or somewhere closer to your AirBnB?

Inside Paddington there are a number of places in the station to grab a take away. If memory serves there’s a Sainsbury, Leon and Upper Crust. Plus other food establishments. I’d opt for getting your take away from here.

FYI not much food wise close to your AirBnB neighborhood. Churchill Gardens is a housing estate.

My train from Cardiff is arriving at Paddington station. I am leaving there to go to my Airbnb and need food.

There are several places in Paddington. Just grab a sandwich at one that looks appetizing

Here is a station map for Paddington:

as you head to Pimlico you may pass Victoria station. If so, in addition to the other sources mentioned by Claudia there is also a food market hall at Victoria with all sorts of food stalls. https://markethalls.co.uk/venue/victoria/

One of the stalls is DF Tacos - very good. I love everything they produce. DF as in Mexico City.

you can also pick things up in Cardiff and eat at your seat on the train.

When I need a good quick take away in London, I always look for a Pret

Within Paddington Station you have an M&S, and Sainsburys for grocery shopping, and WH Smith, and Boots (for meal deal sandwiches/drinks/snacks.) For prepared foods you’ve got 2 Prets, a pasty stall, a sushi outlet and a burrito place. There’s a Starbucks, Burger King, and other takeaway places.

If you have a bit of time there’s Mickey’s Fish and Chips outside the station.

I think there’s a Gregg’s by the Churchill Gardens estate so you should be able to try them at some point.
