Since this word is made up of a single kanji, it should use the kun'yomi reading. When learning the kanji, you didn't learn that reading, so here's a mnemonic to help you with this word:
Think of your favorite shop. Okay, now imagine yourself going to it. When you arrive, the entire shop is totally missing (みせ). Feel the shock and awe of this. It's as if it picked up and left overnight. No building, no anything. Just missing.
Please draw a map from the station to the store.
The restaurant is already fully booked for the rest of the year.
You’re going to love this shop. They have the best meatloaf in the world.
