A stop into Harry Hedgehog & Bunny Cafe on our first day in Tokyo did not satisfy our hunger as the only food served was meal worms for the little hedgehogs.
The little guys were very spikey to hold as they wriggled around trying to escape but the trick was to rub their tummy and they curl up into a ball. Molly was OK without gloves but Em was a bit of wimp.
For about 2,000 yen you get a table to sit down an feed the hedgehogs for 30 minutes. We were able to walk straight in at around midday on a Monday but we noticed queues building as we were leaving and some large queues other times we passed later in the week.
