I think the space between the lines really helps in solving this puzzle.

Its a nightmare!! Lots of guessing very little logic.

Absolutely no clue how to do this after the first for lines of 5 :(

Love that show :)

SPOILER: First word begins in top left corner.

I found it easy to solve but I did have a lucky guess at the name, I think every British person knows it haha.
A clue for people who want it: The title itself is four words, and it's where strangers invite other strangers to eat their food. :)

Spoiler 2: Last word ends in bottom right corner.

Only the last four squares are ambiguous. Thank you for the puzzle.

Thank you.

Probably would have been logical as a 17 x 23 puzzle instead.
