When you're looking for a bit of cheese, sometimes you'll take a small road to the top of a little hill, and that's just what we did. The Looking Glass isn't so much of a cheese shop as a little building outside someone's house - or at least that's what it looks like from the outside - but it's definitely worth the stop. Just look for the "cheese shop" sign and you're there.
Once inside, the place is definitely friendly enough, though there isn't a ton of room - if you happen to be behind someone you can try and squeeze in to hear what's being said, or you might have to wait somewhat uncomfortably while they finish before your turn, and that's about the only problem - it's not a shop in the normal sense, and so there isn't a bunch of room.
As you get to the front of the line to take your turn, however, there are plenty of samples and lots of information to be had from the helpful staff, which allows you to leave with plenty of cheese in your belly even if you don't buy any.
